Although he was just signed on Monday, linebacker Rocky Boiman is going to play today against the Bills. Usually recently-signed players need at least a week or so to learn the system enough to play in a game, but Boiman knows the Lions' defense well enough to see the field tonight.

"That’s the plan, we didn’t bring him in to stand around. That’s part of the reason he’s the guy we brought in ... He’s a guy who can get up to speed really quickly,’’ coach Jim Schwartz said.

I'm still not sure what to think about Boiman's chances of making the team, but I suppose how he performs against Buffalo will shed some light on if he will be kept around past Saturday.
