Fisher says Volek lied to him, let organization down

"There's a difference between assuming a role as a starter and a backup role. There's a distinct difference between those two positions. In the club's opinion based on what transpired, he was not suited to be the starter," Fisher said.

Volek was enjoying what he called a good start Wednesday in his first practice with the Chargers. He said Fisher's comments surprised him and he had no clue why his former coach would say such things.

But he added he had been competing for the starting spot.

"If he wants to say that, he's going to say that," Volek said. "I'm not going to stand up here and argue with him. He's been a great coach for me for six years. When you're losing, when you're 0-2, every little small bruise turns into a large bruise."

For now, the Titans have only Collins and rookie Vince Young on the roster going into Sunday's game at Miami (0-2).

Matt Mauck was signed Wednesday to the practice squad after spending most of last season on the roster. Fisher said they have needs at other positions, which is why they'll stay with only two quarterbacks. But Mauck can be elevated at anytime by signing a contract.

If Collins is hurt during a game, that leaves the Titans with only Young, who has played in spot duty the first two weeks.

Collins must improve after posting a 1.3 passer rating in last week's 40-7 loss at San Diego, and he called the Titans' quarterback soap opera life in the NFL.

"It's a great game, but it can be a tough business. That's the bottom line. Is it always fair? No. I played in New York five years, went to the playoffs two times, they sent me on my merry way. What're you going to do? I mean, move on," Collins said.

Linebacker Keith Bulluck said the quarterback situation has hurt the Titans more on the field than in the locker room.

"You never know who we're going with or which way it's going," Bulluck said. "That's the only way I would say."
