NASHVILLE, Tenn. -- Since he graduated into the Tennessee Titans' starting quarterback in 2012, Jake Locker suffered five injuries that knocked him out of games. No. 6 arrived in Sunday's loss to the Jets as he started in place of the injured Zach Mettenberger.

For Locker, the count means he's suffered an injury that has cost him game action in six of 30 games he's played. That's 20 percent, or one in every five games.

Here's the roster of Locker's injuries.

Left shoulder, at Houston, Sept. 30, 2012: Missed five games.

Right knee and hip, against Jets, Sept. 29, 2013: Missed two games.

Right foot, against Jacksonville, Nov. 10, 2013: Missed seven games.

Right thumb, against Cleveland, Oct. 5, 2014: Missed one game.

Right wrist, at Cincinnati, Sept. 21, 2014: Missed two games.

Left shoulder, against Jets, Dec. 14, 2014: Missed TBD

Fans tend to crush Locker and players like him who can't seem to stay healthy.

He's unlucky, for sure. Some guys are built to withstand stuff better than others. He's not on the high end of that scale. There is only so much he can do to control that, and I'm sympathetic that he's not durable in the way his line of work requires.

Questions about it bother Locker, but he has to understand they are simply part of the deal.

"I've got too many good things in my life, too many blessings in my life to get upset about a few little things like this," Locker said. "Obviously it's frustrating, it's not easy to deal with. But I truly do feel that way."

We'll get an update on Locker from coach Ken Whisenhunt later Monday. The odds that Locker can throw Thursday night in Jacksonville seem very slim. I expect the Titans will sign someone to back up Charlie Whitehurst today.

Locker's contract expires after the season. If he can't play Thursday or on Dec. 28 against Indianapolis, that hit by Jets linebacker Quinton Coples that drove Locker's shoulder into the ground will be his final play for Tennessee.
