Robert Woods ankle injury occurred during Wednesday's Week 3 practice

Buffalo Bills wide receiver Robert Woods suffered an ankle injury during practice on Wednesday that kept him off of the field for the team's practice on Thursday. Right now, it doesn't sound much like he'll be ready to play on Sunday, though things could obviously change on Friday.

Marrone on Woods: "right now he would not be able to play."

If Woods can't play, Mike Williams would draw the start, playing across the formation from rookie Sammy Watkins, who himself is playing at less than 100 percent right now. Marquise Goodwin and Chris Hogan would conceivably see more playing time as the next two receivers in the pecking order.

Then again, this could just be a one-day hiccup for Buffalo's No. 2 receiver.

Just bumped into #Bills WR Robert Woods. He should be fine after being held out of practice today. Sammy said same thing about Woods, too.

Another player that was not on the injury report on Wednesday was added to it Thursday: left guard Chris Williams, nursing a back injury, was limited. He had missed practice time during training camp with a similar ailment (if not the same one), which allowed rookie Cyril Richardson to see plenty of first-team work.

Veteran linebacker Keith Rivers (groin) was also limited for a second consecutive day. The Bills' full injury report for Sunday's game against San Diego will be released on Friday.
