Tennessee Titans quarterback Jake Locker could be out one to months with a serious hip injury, according to ESPN.

Locker is out of the hospital, coach Mike Munchak said Monday as he ruled him out for at least this week's game against the Kansas City Chiefs as the quarterback has a sprained right medial collateral ligament as well as the hip problem.

Although X-rays were negative, swelling needs to go down before a second magnetic resonance imaging exam can be performed. Initial tests were inconclusive, but the team is hopeful that it's not a season-ending injury.

The team doesn't intend to use the injured reserve-designated to return on Locker.

"It's a blow to the team, no doubt about it," Munchak said.

Locker issued a statement through the team: "I want to thank everyone for their thoughts and prayers over the last 24 hours. I am going to work as hard as I can to get back as soon as I can. I believe in this team and will do whatever I can to help us win in the meantime."

Locker was injured on a hit by Jets defensive lineman Muhammad Wilkerson, which didn't draw a flag, but is being reviewed by the NFL.

"If it was late, the ref would have thrown a flag," Wilkerson said. "They didn't throw a flag."

"Obviously, it was unfortunate," Jets coach Rex Ryan said. "Clearly, in my opinion, I thought Muhammad did what you're supposed to do: lower your target. He did that. Obviously, there wasn't a malicious intent on his part at all. In my opinion, I thought it was a clean hit."
