Tennessee Titans linebacker Gerald McRath will undergo season-ending surgery this week to repair a partially torn patella tendon, according to TitanInsider.com.

McRath had tried to play through the injury that worsened on a hard field in Dalton, Ga., on Aug. 6 when the Titans scrimmaged the Atlanta Falcons on a high school field that he described as a "hard field."

“It was a point of pain tolerance. At first it really wasn't that bad. It was something I could get through,” he said. “After Atlanta, going on that hard field, it kind of set me back a little bit, and I'm not where I want to be at all. It's a tough decision to make, and I definitely don't want to leave these guys. I'm going into my fourth year, and there's still a lot left to be proved. I'm positive everything is going to work out.”

McRath was a starter for the Titans as a rookie, but after a four-game suspension in 2010, he became a backup and has been in that role the past two years.
