Boston Celtics coach Doc Rivers says Tony Allen might not be back from an injury to guard Los Angeles Lakers star Kobe Bryant when the NBA Finals begin Thursday night.

"It doesn't look good," Rivers said after practice yesterday. "He couldn't get through even the walkthrough portion."

Allen had some success against Bryant in the regular season, but the Celtics guard injured his Achilles' tendon in a post-practice pickup game during the Eastern Conference finals and hasn't played since.

Allen started the regular-season game against the Lakers in Boston on Dec. 30 - one of just 11 games he started this year - and helped hold the NBA MVP to 22 points on 6-for-25 shooting.

* Miami's Alonzo Mourning, whose season ended when he suffered severe knee and leg injuries in a game last December, said he would like to come back and play one more season, if his body gets healthy, before finally calling it a career.

It's not entirely up to Mourning; his contract with the Heat ends June 30, and he almost certainly wouldn't want to play for any other team.

"I still, in my mind, feel I can contribute," said Mourning, 38, who averaged 6.0 points and 3.7 rebounds in 25 games this season for the Heat.

* Three-time NBA All-Star Kevin Johnson's campaign to unseat two-term incumbent Heather Fargo in today's mayoral election in Sacramento, Calif., has been dogged by old sexual-abuse allegations, complaints about his nonprofit development agency and criticism from gay activists over a remark about gay marriage. It has been a rude awakening for the 42-year-old hometown hero who launched his campaign in March.
