ALLEN PARK, Mich. (AP) Detroit Lions cornerback Darius Slay was on the practice field Wednesday after missing Monday night's game at Dallas with a hamstring injury.
Slay was listed as limited at practice, and so was center Travis Swanson (concussion). Swanson hasn't played since Dec. 4 at New Orleans.
Slay was in the locker room after practice, but would not talk about his status. Detroit hosts Green Bay on Sunday night in a game that will decide the NFC North.
The Lions announced Wednesday they have signed cornerback Crezdon Butler and put defensive tackle Stefan Charles on injured reserve.
