Rams center Scott Wells had knee surgery earlier this month, an arthroscopic procedure to repair torn cartilage.

Wells suffered the injury in his first practice back with the Rams after returning in November from foot surgery. Wells, a Pro Bowler a year ago as a Green Bay Packer, played through the pain in starting the Rams' final six games of the regular season.

The Rams gave up only 1½ sacks in those six games, compared to 2.6 sacks allowed per game in their first 10 contests. The surgery was to the same knee (the right knee) that required surgery last spring during the Rams' practice sessions. After recovering from that initial knee operation, Wells suffered a fractured foot in the season opener against Detroit, sidelining him for nine games.

"It's been a frustrating year for me," Wells said at the end of the season. "This is the first time I've had to deal with an injury that has limited my availability. I don't think I've missed more than two games up to this point in my career due to injuries.
