The Detroit Lions' starting cornerbacks were unable to finish Sunday's game against the Chicago Bears, and it showed. The Bears picked on Darius Slay and Jonte Green down the stretch when they made things a bit interesting with a couple touchdowns and two-point conversions. With the Green Bay Packers coming up next, the Lions can't afford to be shorthanded in the secondary.

So what's the word on Rashean Mathis and Chris Houston? Let's start with Mathis, who left early on because of an apparent concussion. It turns out that Mathis said that he was actually cleared to return by the Lions' doctors, according to Kyle Meinke, but the Bears' doctors did not allow him to come back. The Bears' doctors attended to Mathis first, and they apparently claimed that he lost consciousness, according to Carlos Monarrez. As a result, Mathis wasn't allowed to play, but the fact that the Lions' doctors did clear him seems to be a good sign for his status going forward.

As for Houston, he left Sunday's game with a leg injury, per Dave Birkett. He was on the injury report leading up to the Bears game with a hand injury, so add this to the list of ailments he's dealing with. It's not clear at this time if he could miss next week's game because of the injury.

In other injury news, offensive tackle Jason Fox is closer to returning, per Brad Galli. Fox practiced all week, but he was inactive for Sunday's game. Given how well Corey Hilliard seems to be playing, I wonder if Fox will even start at right tackle when he is healthy enough to play.

Finally, running back Reggie Bush returned to action on Sunday after missing a week with a knee injury. Bush was actually nervous about how his knee would respond to returning, according to Lindsay Czarniak, but his numbers really speak for themselves: 173 total yards and a touchdown.
