The first injury report of the week is out for Sunday night's game between the Detroit Lions and San Francisco 49ers. The two most notable pieces of news for the Lions are that cornerback Chris Houston returned to practice on a limited basis and wide receiver Calvin Johnson did not practice because of a foot injury. It's highly unlikely that the injury is serious enough to put his status for Sunday in jeopardy, so I wouldn't worry too much at this point in the week.

Here's a look at the Lions' full Wednesday injury report:

WR Calvin Johnson (Foot) - Didn't practice

DE Lawrence Jackson (Calf) - Didn't practice

DT Corey Williams (Knee) - Limited in practice

LB Travis Lewis (Quad) - Didn't practice

CB Chris Houston (Ankle) - Limited in practice

CB Bill Bentley (Concussion) - Didn't practice

S Louis Delmas (Knee) - Didn't practice

With Houston returning, his chances of playing on Sunday go way up. Unfortunately, both Bentley and Delmas did not practice on Wednesday. Bentley still needs to be cleared to return after suffering a concussion on Sunday, and Delmas still hasn't practiced since having knee surgery in August. Right now it seems unlikely that he will be back for the 49ers game, although it is only Wednesday.
