Bush, who took a helmet to his left knee in Sunday's loss to Arizona, participated in the portion of practice open to the media for the first time this week.
He said Thursday that he wanted to be on the practice field Friday to see how the knee would respond. He had a sleeve on it, but was running routes and catching passes, and it didn't look like the knee was bothering him too much.
His return to the practice field doesn't necessarily mean he'll be in the lineup Sunday, though. It's certainly a good first step, but the Lions will monitor how the knee reacts to the stress of practice and go from there.
Let's not forget that defensive tackle
The Lions will release designations for Sunday's game at 4 p.m. today on detroitlions.com.
Also back for the early portion of practice were linebacker
Palmer missed practice Thursday with the injury. Carey hasn't practiced since suffering his hamstring injury vs. the Vikings. His return is great news for the Lions special teams units.
Both Delmas and Jones practiced on Thursday, and it's been their normal weekly schedule to sit out Fridays as a maintenance day.
