On Wednesday, Vince Young practiced for the first time since spraining his left knee Sept. 7 and sparking concern after police were called to help search for him. He was limited, but took a few snaps with both the scout team and the first-team offense.

Young didn't talk to reporters and hasn't since Sept. 11 when he explained his mother had overreacted to him taking off without his cell phone. That day he also said he expected he would return as starter once healthy.

Veteran Kerry Collins did speak and said he thought Young was excited to be back on the field.

"I think guys were happy to see him out there. He's going to be a part of what we do from here on out. I see no reason why he can't be a positive force on the offense," Collins said.

Young is the man the Titans used the No. 3 pick overall in the 2006 draft and turned the offense over to in his fourth game as a rookie.

But Collins now is the Titans' starting quarterback, a job coach Jeff Fisher has said the veteran will keep as long as they keep winning. These Titans are enjoying the best start ever in franchise history at 4-0 and among only three remaining undefeated teams in the NFL.
