From Comcast SportsNetBOSTON (AP) -- Boston Celtics star point guard Rajon Rondo will miss the rest of the season with a torn anterior cruciate ligament in his right knee.The news came during Boston's 100-98 double-overtime win over the Miami Heat on Sunday in which Ray Allen returned to his old home court for the first time."New guys are going to get an opportunity now," Boston forward Paul Pierce said. "These guys haven't had a chance to really showcase what they can do."For the past five seasons, Pierce, Allen and Kevin Garnett made up the Big Three. After Allen signed with the Heat as a free agent in the offseason, Rondo joined that group -- and became the team leader with his ability to run the offense.He was chosen as the starting point guard for the Eastern Conference in the All-Star game in Houston on Feb. 17.Now the Celtics hope he can be ready for the start of next season."How far is that?" coach Doc Rivers said, "I don't even know how long that is. Eight months? Nine months? So he'll probably be ready, but I don't know.Rondo injured his right knee in Friday night's 123-112 double-overtime loss in Atlanta, a game in which the Celtics blew a 27-point lead, but Rivers said he didn't know when.He reported to the TD Garden on Sunday for a pregame shootaround but was taken to a hospital after complaining of pain.The initial report was a hyperextended knee, but tests showed the ACL tear.Rivers said he learned about 25 minutes before the game that Rondo wouldn't play. Word of the injury's severity came during the game."He was telling me he thought he pulled his hamstring," Rivers said, "Rondo will be fine. He just will not be fine this year."The team made the announcement during Sunday's win in the nationally televised game that snapped a losing streak that had reached six games despite back-to-back triple-doubles by Rondo."We've just got to rally around each other," Pierce said. "I feel for him. He was having such a good season. It's disappointing news."As Celtics players walked off the court through a tunnel toward their locker room, Rondo, dressed in street clothes, greeted them."I know he's sad. I'm sad for him," starting guard Avery Bradley said. "Whatever Doc wants me to play, that's what I'm going to do."Rondo was averaging career highs of 13.7 points and 5.6 rebounds along with 11.1 assists this season.Still, the Celtics are struggling to remain around .500, finishing the day with a 21-23 record, 2 12 games ahead of the Philadelphia 76ers for the eighth and final spot in the Eastern Conference.The Celtics have no true point guard behind Rondo. Rivers said he didn't know if they would try to add one.Jason Terry, known for his outside shooting, Courtney Lee, Leandro Barbosa and Bradley are the other guards. Each played at least 25 minutes Sunday with Lee starting in Rondo's place."We knew something was up at the beginning, but we didn't know how serious it was," Lee said. "Nobody can fill his shoes. That's what makes him great. So the only thing we can do is work as hard as possible and keep the momentum going from this game and have no letup."Rondo suffered a dislocated left elbow in the playoffs on May 7, 2011, when he became entangled with Miami's Dwyane Wade.Boston won 97-81, but Miami won the next two games to clinch the second-round series in five games.
MEMPHIS, Tenn. (AP) — Doug McDermott scored a career-high 31 points, Jimmy Butler had a pair of key baskets in the closing minute and the Chicago Bulls beat the Memphis Grizzlies 108-104 on Sunday night.
The Bulls broke a 104-all tie with 25 seconds left on a 15-footer from Butler and a pair of free throws by McDermott. Butler also had a go-ahead 18-footer with 53 seconds left and finished with 16 points to help Chicago win its second straight.
Taj Gibson finished with 18 points and eight rebounds for the Bulls.
Mike Conley led Memphis with 28 points and eight assists, and Marc Gasol had 24 points and 11 rebounds.
Chicago was without second-leading scorer Dwyane Wade, who did not play on the second night of a back-to-back after the Bulls beat New Orleans at home Saturday.
The game featured 16 lead changes and 11 ties, with neither team holding a double-digit lead.
Most of McDermott's damage came in the first half after the Bulls struggled shooting in the latter part of the first quarter. McDermott came off the bench to reverse the trend.
McDermott scored 20 points in the first eight minutes of the second quarter, moving Chicago's lead to eight. He had 22 points for the half and the Bulls led 52-46 at the break.
Bulls: Nikola Mirotic missed his fourth straight game dealing with an illness. ... F Paul Zipser, a rookie from Germany, started his second game and second straight after coming off the bench in his first 10 appearances this season. ... McDermott converted a four-point play in the second quarter. ... McDermott's 22 first-half points were more than his total for the four previous games (21). ... Chicago scored 14 points in the first quarter, a season low for the opening frame. ... The Bulls are now 4-5 on the second night of back-to-backs.
Grizzlies: Gasol made a pair of 3-pointers in the first half, marking 17 games this season he has made multiple shots from outside the arc. ... Memphis made 11 3-pointers in the game and has converted at least 10 3s in 20 games this season, including 11 of the last 14 games.
This is the 15th season Memphis has hosted a game on Martin Luther King Jr. Day weekend. The Grizzlies are 6-9 in the holiday game.
In recognition of the holiday, Memphis wore special MLK50 Pride uniforms. The black jerseys have sea foam blue numbers, letters and piping with the full T-shirt look instead of the normal sleeveless. The piping replicated the railing in front the rooms at the Lorraine Motel, where King was assassinated in 1968, and the blue color was similar to the doors on the rooms.
Wade's absence meant missing a reunion with Memphis coach David Fizdale. Both left the Miami Heat organization after last season - Wade signing with the Bulls and Fizdale getting his first head coaching job in Memphis. Fizdale said he is sort of a "basketball romantic" and would like to have seen Wade retire in Miami. But he predicted after the player's career "his statue will be out front and (Wade) will be remembered as the great player that he should be."
Bulls: Return home to face the Dallas Mavericks on Tuesday night.
Grizzlies: Memphis travels to Washington to face the Wizards on Wednesday night.
