According to Geoff Hobson of Bengals.com, the Bengals fear the worst for cornerback Leon Hall, who left the game with an achilles injury, and they also lost defensive tackle Devon Still:
"In a devastating first quarter, the Bengals feared they had again lost arguably their best defensive player for the season when cornerback Leon Hall suffered an Achilles injury for the second time since 2011.Hall, who missed the rest of the 2011 season after he tore his left one Nov. 13 against the Steelers, was working on Pro Bowl wide receiver Calvin Johnson in the end zone early in the game, leaped up, and tipped it away, and immediately grabbed his right foot. He buried his face in the turf and went to the bench visibly upset before he was carted off. The club announced an Achilles injury, didn’t say if it was torn, and said he wouldn’t return to the game."
It now unfortunately look like it is a torn Achilles::
Bengals CB Leon Hall did in fact tear his Achilles, a season-ending injury.
