Sunday's game was a rough one for the Detroit Lions and Cincinnati Bengals from an injury standpoint. Several Bengals defenders went down with injuries over the course of the game, and the Lions lost a couple of key players to injuries as well.
Perhaps the most notable injuries for the Lions involved their starting offensive tackles. Left tackle Riley Reiff left in the first half with a hamstring injury, and he was replaced by rookie LaAdrian Waddle. Reiff remained out until the fourth quarter, at which point he was forced to play hurt because right tackle Corey Hilliard went down with a knee injury. (Dylan Gandy would have come in at right tackle had Reiff not been able to give it a go.) There's no word on Reiff's status, but Hilliard is scheduled to have an MRI on Monday.
On the defensive side of the ball, cornerback Rashean Mathis wasn't able to make it through Sunday's game because a groin injury, which he originally suffered last week. Mathis was actually playing relatively well, especially compared to Chris Houston, who was benched at one point in favor of Darius Slay. With Mathis out, the Lions had to go with Houston and Slay to finish the game.
Finally, running back Reggie Bush declined to speak with the media after Sunday's game because of a sore neck. That may have simply been an excuse to avoid the media, but it doesn't sound like anything serious anyway.
