Injuries are part of the game and no player or team is immune from succumbing to the devastation they’ve been known to leave in their wake. But at some point, you have to throw your hands in the air and yell “seriously?!?!”

The SEC has seen its share of injuries this summer. The injury bug got so bad in Tennessee during camp, for example, that head coach Butch Jones placed a kibosh on anyone in the program from talking about ailments to the media.

Here’s a look at six injuries from this summer and from preseason camp that will have an impact in the SEC this season:

Arkansas RB Jonathan Williams

Jonathan Williams’ regular season-ending left foot injury doesn’t spell the end of the Arkansas Razorbacks 2015 campaign before it starts, but losing your incumbent rushing leader and preseason second-team All-SEC performer is never a good thing. The senior was expected to be the featured weapon in a two-headed backfield tandem with Alex Collins. The duo was the only pair of SEC teammates to each rush for more than 1,000 yards last season. Williams is expected to make a full recovery and hasn’t used his redshirt yet, though he’s likely to head for the NFL. Attempting to replace Williams’ 1,190 yards and 12 touchdowns from last season is junior Kody Walker and freshman Rawleigh Williams III — two players with a combined 250 career rushing yards.

Missouri DT Harold Brantley

Harold Brantley is probably lucky to be alive after a June car wreck severely wounded the Missouri junior. The Hershey, Pa., native was poised to rank among the nation’s best run-stuffing and pass-defending defensive linemen this year and improve upon his 5.0 sack, 54-tackle sophomore campaign. Brantley was supposed to be a leader while setting himself up to be among the best defensive tackles at next year’s NFL draft. How well he can recover from a broken left leg and ligament damage in his knee will be answered in time. Without Brantley, Missouri’s front defense is suddenly thin, considering the senior was the lone Tiger with starting experience on the unit. Gary Pinkel already had the task of replacing Shane Ray, Markus Golden, Lucas Vincent, Matt Hoch and Marcus Loud. Now, the defensive line, perennially one of the team’s strengths, is among Missouri’s concerns.

LSU S Jalen Mills

Jalen Mills has started all 39 games of his career in Death Valley. However, the senior safety, the leader of LSU’s vaunted secondary, will start the 2015 season on the bench. Mills suffered a lower leg or ankle injury on Aug. 19 that will keep LSU’s veteran defensive back sidelined for anywhere from four-to-six weeks.

LSU is deep in secondary. Rickey Jefferson should fill in for Mills. He played safety last season in the Tigers’ nickel package, sending Mills to cover the slot receiver. Dwayne Thomas likely takes over those duties. Regardless of who steps in for Mills, it won’t be easy replacing 186 career tackles and 6 interceptions.

The senior has set the Sept. 19 matchup against Auburn as a goal for his return.

Vanderbilt WR C.J. Duncan

The Commodores have faced uncertainty at quarterback practically since the program hired Derek Mason away from Stanford in January 2014. The rest of the offense suffered after the departures of receivers Jordan Matthews and Jonathan Krause.

Duncan, who made 28 catches and averaged nearly 16 yards per reception last year, was supposed to become a No. 1 option at receiver, someone the team could pair with starting running back Ralph Webb and tight end Steven Scheu to give the offense a lift.

Vanderbilt lost its left tackle for the season, in addition to Duncan, putting even more strain on an already-challenged offense.

Florida LB Antonio Morrison

Antonio Morrison’s cranky knee has required two surgeries since the Florida linebacker first injured it against East Carolina in January’s Birmingham Bowl. The Gators and Morrison are being tight-lipped regarding the extent of the injury and no timetable has been set for the linebacker’s return.

Morrison is participating in non-contact drills during preseason camp, with Florida’s contingent of coaches and players only revealing that he’s ahead of schedule, nothing more.

The senior led the team in tackles last year with 101 and has 191 in three seasons in Gainesville. There’s speculation that he could return for SEC play or be out the entire season. Time will tell. New head coach Jim McElwain likely will start Jarrad Davis and Alex Anzalone at linebacker in Morrison’s place if needed.

Tennessee LG Marcus Jackson

Tennessee has endured a rash of injuries this summer. Chief among them is one suffered by starting left guard Marcus Jackson.

The fifth-year senior and most-veteran member of the Vols’ offensive line with 12 starts in 24 career games, Jackson was lost for what’s thought to be the entire season with a torn biceps — at the very best, he could return for the end of the season or for a bowl game. The injury hurts a Tennessee run game led by running backs Jalen Hurd and Alvin Kamara, as well as mobile quarterback Joshua Dobbs.

The Vols also have lost backup guard Austin Sanders and nickelback Rashaan Gaulden.

Six Impact Players Expected Back

Auburn DE Carl Lawson

This is music to the ears of Auburn fans everywhere. Carl Lawson is on track to start the Tigers’ season opener Sept. 5 against Louisville. The disruptive defensive end missed all of 2014 recovering from a torn ACL. Lawson racked up 4.0 sacks and 7.5 tackles-for-loss as a true freshman in 2013. Coach Gus Malzahn has described Lawson as “unblockable” in practice this preseason. Despite the gushing, Malzahn has held Lawson out of practices and a recent scrimmage to avoid another debilitating injury before the season even starts.

Ole Miss LT Laremy Tunsil, WR Laquon Treadwell and LB Denzel Nkemdiche

The last we saw Laremy Tunsil, the Ole Miss left tackle was flashing the Peach Bowl crowd a thumbs up as a golf cart hauled him and his broken fibula and dislocated ankle out of the Georgia Dome. Two months earlier, it was WR Laquon Treadwell exiting the Auburn game with the same injury. Treadwell is an All-SEC receiver with 1,240 career yards and 10 touchdowns. Tunsil is projected to be an NFL draft pick, having only allowed two sacks during his 23-game career. Both have been cleared to play, but have seen limited action this summer. Having Tunsil, Treadwell and Denzel Nkemdiche (broken ankle) in the lineup after such major injuries is a game-changer for Ole Miss.

Alabama RB Kenyan Drake

Kenyan Drake appears fully recovered from the broken leg he suffered against Ole Miss last season. Now if he can just get his hamstring healthy, the Alabama running back might be able to add to his 1,087 career rushing yards and 17 touchdowns. The senior sat out the Tide’s recent scrimmage due to a wonky hamstring, but is expected to team up with Derrick Henry out of Alabama’s backfield. He’s worked with the wide receivers some this summer as well and should get plenty of pass targets.

Auburn LG Alex Kozan

Alex Kozan returns to Auburn for his fourth season with the Tigers. Unfortunately, due to a redshirt freshman year and a back injury that cost him last season, the left guard has only one year’s worth of true game experience. That one season, however, was a big one for the 6-foot-4, 300-pound freshman All-American. Kozan is back in practice this summer and apparently healthy, but he hasn’t totally reclaimed his starting role yet as he continues to be pushed in camp by Devonte Danzey. The latter filled in admirably during the redshirt junior’s absence. Regardless of who wins the starting nod, it’s safe to say Auburn is stacked at the position.
