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.
