JACKSONVILLE, Fla. -- Tennessee Titans quarterback Vince Young left the game midway through the first quarter when he fumbled the snap and Terrance Knighton of the Jacksonville Jaguars fell on his left leg.

Young, who threw a 23-yard touchdown pass to Kenny Britt on the opening drive, was helped off the field. The Titans said he sprained his left knee.

"He's a little sore," coach Jeff Fisher said, adding that Young also sprained his left ankle. "He could have finished in shotgun."

Young was replaced by Kerry Collins, who led the Titans to a 30-3 victory over the Jaguars.

"Kerry did a nice job and that's why Kerry's here," Fisher said. "We're very, very fortunate that we have two very good quarterbacks."

Collins completed 11 of 16 passes for 110 yards and a touchdown, directed five consecutive scoring drives and put the Titans (4-2) atop the AFC South.

Two years ago at Jacksonville, the Jaguars knocked Young out of the game in the season opener. Collins replaced him, the Titans went on to win the game and he took them to the playoffs. The year was memorable for Young going into a deep funk.
