Tennessee Titans linebacker Gerald McRath will have surgery on his left knee this week and is out for the season, coach Mike Munchak said on Sunday, according to CBSports.com.
McRath missed the final three games of last season with knee and ankle problems.
McRath has been bothered by knee problems in the offseason, and he said he thinks he aggravated the injury making a tackle on a second-quarter kickoff on Aug. 11 at Seattle.
He has started 12 games during his previous three years in the NFL, but did not start in any of the 12 games he played for Tennessee last season, when he had 10 tackles and four assists.
He's in the last year of a four-year, $2.176 million contract.
The Titans probably will decide on Monday whether Jake Locker or Matt Hasslbeck will start in Thursday's preseason game against Arizona.
