ALLEN PARK, Mich. -- Jason Fox started the first game of his career Sunday against Minnesota. He didn’t get to finish it.

Now, the fourth-year pro out of Miami (Fla.) is back to waiting to when he can return to the field after he injured his groin in the first half against the Vikings.

“These things happen in football,” Fox said Wednesday. “I came out, knew Corey [Hilliard] was going to play great, which he did, and now I’m just working to get back.”

Whether or not that can happen this week is still a question. Fox did not practice Wednesday and didn’t know when he would be returning to the lineup. He was hopeful to return this week.

If Fox can't play, Hilliard will likely take his place at right tackle.

“I’m going to try my hardest,” Fox said. “I’m working to get back as soon as possible. If they let me go this week, great. If not, I’ll be back as soon as possible.”

Defensive tackle Nick Fairley (shoulder) and safety Don Carey (hamstring) also did not practice Wednesday. Safeties Louis Delmas (knee) and John Wendling (ankle) were limited along with defensive end Jason Jones (knee).

Running back Reggie Bush, who injured his groin and finger in Sunday’s win over Minnesota, practiced fully.
