ALLEN PARK — Reggie Bush, who injured his knee in the second quarter on Sunday, said today (Thursday) that he is optimistic that he’ll be ready to play on Sunday in Washington.

“It’s a long ways until Sunday, I’m optimistic about playing, I always am,’’ Bush said. “Today was a good day. The progress since last Sunday has been really good. It’s a lot further than I expected. 

“It feels a lot better than I thought it was going to feel so I’m happy where it is right now,’’ Bush said. “Today was a very positive day so we’ll see what happens tomorrow.’’

Bush hasn’t practiced this week, instead he’s been getting therapy.

The Lions running back said nothing was torn in his knee which was a good sign. He was not specific with the diagnosis.
