Coach: Titans had reason to be worried about QB Young; Simms signed

"I'm happy to report he's home. He's resting. He's completed the MRI. Don't have the results yet, and we're hoping he can get that knee healed up and can get back on the field as soon as he can," Fisher said on his radio show.

With only veteran Kerry Collins healthy and Kansas City preparing to sign Ingle Martin off the Titans' practice squad, Fisher said they had agreed to terms with Chris Simms after working out Quinn Gray, Joey Harrington and Doug Johnson earlier Tuesday.

Young's agent said there was no need for concern because the quarterback was at a friend's house watching football and eating chicken wings during the four hours when no one could find Young.

"When people were worried about him, I was on the phone talking to him," agent Major Adams said. "I didn't know there was any confusion about where he was as if he was missing or whatever. He just said, 'Hey, I'm over here watching the game.' ... Then I start getting all these frantic calls."

Fisher was asked if he was concerned by Young's sideline demeanor. Fans have been upset thinking Young didn't want to go back onto the field following his second interception, and the Titans have defended him as an intense competitor.

"It is an issue, and it is something we're working with him to kind of correct," Fisher said of Young's emotional reactions. "Our game is a very, very emotional game. There's going to be ebbs and flows at times, good plays and poor plays and negative things that happen. Different players deal with it differently."
