The Bears' Chris Williams is expected to play Sunday after missing the previous three games with a right hamstring injury, but he'll line up at a new position.

Williams, who previously had played left and right tackle during his three seasons with the Bears, will move to left guard. The move came as a surprise, considering the Bears had given no indication of an intent to play the 2008 first-round pick anywhere other than at left tackle.

Frank Omiyale, who had been playing left tackle when Williams was sidelined, is expected to continue at that spot. Olin Kreutz will remain at center, Edwin Williams will get his second consecutive start at right guard and rookie J'Marcus Webb likely will start at right tackle again. Roberto Garza, who had started every game this season at left guard, appears to have been demoted.

The way we see it

Some will say this is a move the Bears should have made long ago. There were skeptics before Chicago drafted Chris Williams when it came to his chances of succeeding at left tackle. We don't know if it's a permanent move or not, but the Bears are going to continue tinkering until they find a combination on the O-line that satisfies them.
