Holmes' career in doubt after injury move by KC

KANSAS CITY, Mo. -- Priest Holmes, who hasn't practiced at all in training camp, now will miss at least the first six weeks of the regular season and his career is in doubt.

Kansas City put the three-time Pro Bowl running back on the physically unable to perform list Monday. He will be out for a minimum of six weeks, then the Chiefs will have 21 days to activate him.

Holmes, who turns 33 in October, missed the last nine games of the 2005 season after taking a hit from San Diego's Shawne Merriman that caused trauma to the head and neck, and doctors still haven't given him medical clearance to practice or play.

"Obviously, he's not prepared to play at this point," said coach Herm Edwards. "You never know where his career's at right now. Only he knows that. That's between he and the doctor."

While Holmes was gone, Larry Johnson took his job with a spectacular nine-game spurt that ended in a team-record 1,750-yard rushing season.

Under league rules, Holmes will be on the PUP list a minimum of six weeks, and then the Chiefs will have 21 days to activate or release him.

Holmes has rushed for a club-record 5,933 yards and, in 2003, a then record 27 touchdowns.

Quarterbacks

Kerry Collins and Jeff George are back in the NFL.

Collins, who spent the last two seasons with Oakland, signed with Tennessee, which decided it needed more experience after trading away Steve McNair.

Coach Jeff Fisher said Billy Volek remains the starter for now, with rookie Vince Young backing him up while Collins learns the offense.

"Billy's got some competition," Fisher said. "I've spoken with Billy. Billy's not too awfully pleased with it. But that's life in the National Football League."

George, meanwhile, signed with the Raiders, although he hasn't thrown a regular-season pass in the NFL since 2001.

Both are former first-round draft picks. George was the first overall pick by the Colts in 1990 and Collins was Carolina's first-ever pick, fifth overall, in 1995.

Collins went 7-21 as the starter in Oakland the past two years. He completed 302 passes for 3,759 yards in 2005 and 20 touchdowns, but was sacked 39 times and threw 12 interceptions.

Collins has played for Carolina, New Orleans, the New York Giants and Raiders in an 11-year career.

Known for his strong arm and clashes with coaches, George has a 46-78 career record as a starter.
