ORCHARD PARK, N.Y. -- On the field, Buffalo Bills wide receiver Sammy Watkins showed few ill-effects of a preseason rib injury during Sunday's 29-10 win over the Miami Dolphins.

On the sidelines during that game, however, Watkins was visited several times by team medical staff and at one point was hunched over near the bench area after returning from play.

Watkins was listed as a full participant during practice this week and says his condition is improving.

"I'm feeling pretty good. Just day by day, it gets better," he said. "I just have to keep working and keep getting stronger."

After catching three passes in the season opener, Watkins had eight receptions for 117 yards last Sunday. Watkins missed only three snaps (of 57 total) in Week 1 and nine snaps (of 59 total) in Week 2.

The fourth overall pick didn't offer a time frame on when he may be back to full strength.

"I don't know how long. It's just a nagging injury," he said. "It's something that you can play with. Hopefully it stops. Whenever it stops, I'll be fine. But right now I just have to play through it."
