Titans wide receiver Kenny Britt underwent arthroscopic surgery on his left knee according to Jim Wyatt of the Nashville Tennessean. Britt tore the ACL and MCL in his right knee last September and required a second procedure, described as a "cleanup" by coach Mike Munchak, in May. The Titans said at the time he would be ready for the Sept. 9 season opener against the Patriots. It was not immediately known why Britt required a procedure on his right knee or if he's still on course to return for the start of the regular season. The Titans equipped themselves with better depth to withstand injuries at the position in the offseason, including first-round pick Kendall Wright, who general manager Ruston Webster said was "an advanced rookie" during minicamp in May. Britt had 289 receiving yards in the first two-plus games before he was injured in the Titans' third game of the 2011 season. He missed four games in 2010 with a strained hamstring.
