Alabama didn’t escape its first scrimmage of spring practice unscathed.

Freshman Bo Scarbrough injured his knee near the end of Friday’s practice. The Crimson Tide did not know the extent of his injury immediately, but indications are it could be serious. The team will run tests to determine if Scarbrough has torn his ACL, TideSports.com reported.

“You’ve got to take MRIs and do all those things, so I don’t speculate on these kind of injuries,” coach Nick Saban said, according to multiple media reports. “We’ll see, and we’ll let you know when we find out.”

The 6-foot-2, 240-pound Scarbrough, a former five-star athlete from Bradenton, Fla., did not qualify academically as a member of the 2014 recruiting class. He joined the team in time for bowl practice last December, however.

A versatile back, Scarbrough was getting practice reps behind Derrick Henry, Kenyan Drake and true freshman DeSherrius Flowers in practice.

“Bo was doing pretty well,” Saban said Friday, according to AL.com. “But we’ve had a lot of injuries, suspensions, and lost some people at that position. So what seemed like a pretty strong position depth-wise has gotten a little thin.”

Five-star running back Damien Harris will join the team this summer. Assuming Scarbrough’s injury is as bad as it is feared, the Tide will need contributions from Flowers and Harris, especially if offensive coordinator Lane Kiffin uses Drake to catch passes, as it’s been suggested he will.

Altee Tenpenny elected to transfer after last season, and Tyren Jones, already suspended indefinitely, got kicked off the team after an arrest for marijuana possession this week. T.J. Yeldon and fullback Jalston Fowler are headed to the NFL draft.

Henry and Drake are the only two running backs with double-digit college carries on the roster.

Scarbrough rushed for 36 yards on 16 carries in Friday’s scrimmage, according to TideSports.com, while Henry led the team with 112 yards on 11 carries. Drake continues to work his way back from a catastrophic injury, and reportedly ran a 4.44-second 40-yard dash during spring testing.

“Kenyan has been able to do everything,” Saban said. “I can’t say that he’s 100 percent, but I think that — the big thing we’re trying to do is to get him all the reps we can get him, but not bang him around too much that he has a problem with his ankle and then once we get through the spring he’ll have a significant amount of time to be able to get some rest and get in better condition, but he’s really done well.”

In addition to Scarbrough’s injury, receiver Cam Sims recently tore his ACL, defensive back Geno Smith got arrested on his second DUI charge and defensive lineman Jonathan Taylor got kicked off the team following an alleged domestic abuse (his accuser later rescinded her allegations).

If you’re an Alabama fan, are you holding your breath wondering what’s next at this point?
