Williams: Sore groin holding me back
Williams, who sat out Week 2 because of the sore groin, was seen riding a stationary bike on the sidelines during the Packers game in an attempt to stay loose.
"I'm good to play, it's just sitting on the sidelines sometimes, especially in the Chicago weather where it's chilly, not as hot ... I just have to keep that thing warm," Williams said. "That's why I get on the bike.
"It's holding me back a little bit. It's not 100 percent, I mean it's just Week 3 of this thing. But it's a lot better than what it was. I'll be good to go."
Quarterback Jay Cutler and Williams were unable to connect on four pass attempts in Week 3. Two balls intended for Williams were intercepted by Green Bay safety Morgan Burnett, one was dropped on the goal line, and the other was overthrown. Williams is unsure when his chemistry issues with Cutler will be resolved.
"I mean who knows, who knows. It varies from player to player, so you just have to keep grinding and just keep going at it day and day," Williams said. "When it goes off, we'll be good.
"It (the Packers game) was my fault. Put it on me, especially the touchdown. I have strong enough hands, especially with the contact that I got. It was a great hit by him, but I still have to hold onto that ball. The four balls that I got, I should have caught them."
Williams caught four passes for 55 yards in the Bears Week 1 victory over Atlanta.
"The groin is just something you have to be patient with," Martz said of Williams. "He tried to play with it and did OK. I know it was bothering him a little bit. He should be a lot better this week ... like he did in the opener. He was terrific in the opener. I think that's who he is.
"I think the combination of him and Johnny [Knox], when you look at the opener when they were both healthy and really going, that's pretty good. That's what you would want at that position. That position combined, 90 catches maybe and a whole lot of yards, and between the two of them, that's certainly a possibility."
