BOSTON -- Paul Pierce hit a go-ahead jumper with 31 seconds left in the second overtime and the Boston Celtics beat the Miami Heat 100-98 on Sunday, then learned All-Star point guard Rajon Rondo will miss the rest of the season with a knee injury.
Rondo will have surgery for a torn anterior cruciate ligament in his right knee. He was hurt late in Boston's 123-112 loss, also in two overtimes, to the Atlanta Hawks on Friday night.
It was the first game in Boston for Ray Allen since he left the Celtics after five seasons and signed as a free agent with Miami. He scored 21 points.
Kevin Garnett had 24 points and 11 rebounds, and Pierce added 17 points, 13 rebounds and 10 assists for the Celtics, who ended a six-game losing streak, their longest in six seasons.
LeBron James scored 34 points for the Heat, who had won four in a row.
LAKERS 105, THUNDER 96
Pau Gasol scored 16 points in a reserve role as the Lakers picked up the most impressive victory of their thoroughly unimpressive season, coolly maintaining a small lead down the stretch of their second straight win after a four-game skid.
Los Angeles had lost nine of its last 11 against the powerful Thunder, including four of five in the clubs' second-round playoff series last spring.
KNICKS 106, HAWKS 104
NEW YORK -- Carmelo Anthony tied a franchise record with nine 3-pointers, then converted a go-ahead, three-point play with 12.5 seconds left to cap a 42-point night and lead the Knicks to the victory.
The Hawks shot a season-high 60 percent from the field but had their three-game winning streak snapped when Josh Smith, burned on Anthony's basket, missed a 3-pointer on Atlanta's final possession.
Amare Stoudemire and J.R. Smith each had 18 points for the Knicks, who were 16 of 27 (59 percent) from 3-point range. Raymond Felton had 12 points and 10 assists in his second game back after a 10-game absence with a broken right pinky.
CLIPPERS 96, TRAIL BLAZERS 83
LOS ANGELES -- Blake Griffin had 23 points and nine assists, helping the Clippers stop a four-game losing streak.
Clippers star Chris Paul missed his fourth straight game and seventh in the past nine because of a bruised right kneecap. Eric Bledsoe had 10 points, five assists and five rebounds in his seventh start at point guard, and Lamar Odom added eight points, 13 rebounds and six assists.
All-Star forward LaMarcus Aldridge led the Trail Blazers with 21 points and 11 rebounds. It was Portland's seventh loss in nine games, and it came in the second part of a home-and-home set with the Clippers.
Portland trailed 74-59 after a driving layup by Bledsoe with 3:15 left in the third quarter. Griffin didn't play after going to the bench with 10 seconds left in the third and the Clippers leading 78-62.
MAVERICKS 110, SUNS 95
It was the 10th straight home win for the Mavericks against the Suns, who haven't won in Dallas since March 14, 2007.
Nowitzki passed Iverson for 18th on the NBA's scoring list with a third-quarter jumper that stopped a Phoenix run, and his 3-pointer early in the fourth started a surge that put Dallas in control for good.
Phoenix rallied from a first-half deficit and made it interesting for a second straight night in Texas after losing at Western Conference-leading San Antonio. Goran Dragic led four players in double figures with 18 points.
HORNETS 91, GRIZZLIES 83
MEMPHIS, Tenn. -- Ryan Anderson scored 22 points for New Orleans, connecting on seven 3-pointers.
Anderson was 7 of 13 from the field, all of his attempts coming from outside the arc. Fellow reserve Jason Smith was 5 of 7 from the field for 16 points, and Anthony Davis was the only New Orleans starter to finish in double figures with 10 points.
The Hornets had dropped consecutive games.
Zach Randolph led Memphis with 20 points and 13 rebounds for his league-leading 28th double-double. Marc Gasol had 14 points and 11 boards, and Jerryd Bayless also scored 14. Rudy Gay had 10 points, but was 3 for 17 from the field, including a 1-for-7 performance from long range.
New Orleans put the game away by outscoring Memphis 27-15 in the fourth quarter.
PISTONS 104, MAGIC 102
The Magic had a chance to tie the game in the closing seconds after a missed free throw, but missed three putback attempts.
The Magic have lost five straight games.
