Timetable for return still uncertain

New England Patriots offensive lineman Matt Light has no ligament damage in his knee or ankle, team sources told ESPN NFL Insider Adam Schefter, but his timetable for returning to the field is still uncertain.

Light, who injured his right knee in Sunday's Patriots loss to the Broncos, was seen using crutches Monday in the Patriots' locker room.

He was injured in pass protection on the first play of the fourth quarter Sunday, an 11-yard completion from Tom Brady to Wes Welker. He was attended to by trainers on the field before being helped off. After being examined on the sideline, he departed for the locker room and did not return.

Light moved gingerly on the crutches Monday, not putting weight on the injured knee.

Rookie tackle Sebastian Vollmer drew increased media attention Wednesday as he figures to be the top candidate to replace Light in the starting lineup.

Vollmer, who has appeared in all five games this season, saw game action as part of a jumbo package when the Patriots utilized Light as a third tight end. Vollmer filled the veteran's void in the fourth quarter Sunday vs. the Broncos.

One scenario the team's tackles also are bracing for is Nick Kaczur, the starting right tackle, moving to left tackle, and Vollmer starting at right tackle.

"If that's what they want, I've done it before," Kaczur said. "It's the coaches' decision. If that's what they want, that's what we'll do."

Light has started 59 consecutive games since the 2005 season, when injuries limited him to only three appearances. During a nine-year career, Light has played in 118 games (starting all but two).
