NASHVILLE, Tenn. -- Titans quarterback Vince Young practiced on a limited basis Wednesday but lost one of his favorite targets when tight end Bo Scaife was placed on injured reserve with a lacerated liver.
Scaife won't be available for the playoffs. Tennessee plays at San Diego in the first round Sunday, and Young hopes to start despite a sore right quadriceps.
The team's third-leading receiver with a career-high 46 catches for 421 yards, Scaife was hurt during Tennessee's 16-10 win over Indianapolis on Sunday night. He was trying to catch a high pass from Young when he was hit by Colts safety Matt Giordano in the second quarter.
The ball bounced off Giordano's head, and Titans receiver Justin Gage caught it just before it hit the ground for a 21-yard completion.
The tight end finished the game and returned with the Titans to Nashville. But coach Jeff Fisher said Scaife had a tough night, underwent some tests and was hospitalized on Monday. Scaife was released Wednesday morning but was placed on injured reserve and will need up to six weeks of rest to heal.
"Bo's been a big-play guy for us in his own way," Fisher said. "He's kind of a leader on offense. He's out there every day, gets up after most big hits. This one, he did. He came back and played. It's a difficult situation for Bo. We've got people on the roster that are going to have to step up."
Young said he apologized to Scaife, his college teammate at Texas, for putting him in a position to be injured.
"It hurts a lot because I was one of the guys that got him hurt. That's my brother, friend, everything, all of the above," Young said.
The Titans still have two four-year veterans at tight end in Ben Troupe and Ben Hartsock, who have combined for 17 catches this season. The team also promoted tight end Jamie Petrowski from the practice squad to the active roster and added tight end Leonard Stephens to the practice squad.
Young left the game against Indianapolis with an ailing right quadriceps, an injury that kept him out of an Oct. 21 win at Houston.
Center Kevin Mawae, who has missed the past two games with an injured left calf, sat out practice with right guard Benji Olson, defensive tackle Albert Haynesworth and defensive end Antwan Odom.
Running back Chris Brown (back) did not practice, and LenDale White (knee) was excused for personal reasons.
Wide receiver Roydell Williams, tied for the team lead in catches with 55, hurt his right ankle during practice and had to leave the field. Fisher said he did not know the extent of the injury.
