Celtics guard Allen out for season with knee injury

BOSTON -- Boston Celtics guard Tony Allen will miss the rest
of the season with two torn ligaments in his left knee.

Coach Doc Rivers said Thursday that Allen will be out at least
six months. Allen hurt the knee when he landed awkwardly after an
uncontested dunk in the final minutes of a 97-84 loss to Indiana on

Rivers said Allen "was not in good spirits" when he spoke with
him earlier Thursday.

"As a coach, you can be emotional, but you still have to
function," Rivers said. "He came to believe he could be a great
player in this league and now he has to start over again."

The Celtics have already lost leading scorer Paul Pierce, out
since Dec. 20 with a stress fracture in his left foot. Forward
Wally Szczerbiak is out at least a week because of ankle injuries
and guard Delonte West is out with a sore back.

Center Theo Ratliff is out for the season with a back injury.
