Former Florida standout CB CJ Henderson is battling a serious groin injury, and the Jacksonville Jaguars have placed him on the injured reserve, which means he’s out for at least three weeks.

Henderson was a first-team All-SEC pick in 2019 after he appeared in nine games and made 33 tackles and 11 passes knocked down. He skipped the Gators game at the Orange Bowl to prepare for the NFL Draft. Henderson was a three-year starter at Florida and led the team with those 11 pass breakups last season despite missing several games with an ankle injury.

The No. 9 overall pick in that draft, Henderson has six pass breakups and one interception and has started eight games this season. Henderson did not play earlier this season against Houston because of a shoulder injury.

Last week, he forced a fumble against Green Bay.

In the season opener, he had five tackles, an interception and three pass breakups, including one on fourth down late in the fourth quarter that helped propel the Jaguars to an upset victory against the Indianapolis Colts.

Henderson will miss games against the Steelers, Browns and Vikings.

He will be eligible to return to practice on Dec. 10. Once a team activates a player from IR, it has to return him to the active roster within 21 days.
