ALLEN PARK — Lions defensive tackle C.J. Mosley, who was added late to Wednesday’s injury report, did not practice today (Thursday) because he's a new dad. 

Also left guard Rob Sims didn’t practice because he was under the weather. A flu bug has gone through the locker room since last week.

Defensive end George Johnson, who missed on Wednesday with an illness, returned to work on Thursday.

New cornerback Josh Thomas, who was claimed off waivers from the Jets, was at work wearing No. 24.

Nick Fairley (knee) also did not practice.

The Lions practiced in outdoor temps of 31 degrees in preparation for the game at Chicago on Sunday. The forecast for the Windy City is 38 and sunny.
