Miami Heat President Pat Riley has added another chapter to his rivalry with the Boston Celtics.

After LeBron James complained about calls and Boston Celtics president of basketball operations Danny Ainge chided him for it, Riley lashed back Friday night.

Riley’s response: “Danny Ainge needs to shut the [expletive] up and manage his own team.”

This saga started Wednesday after Miami’s 27-game winning streak ended in Chicago. James told reporters that night that he does not believe some of the hard fouls he takes are “basketball plays.” A day later, Ainge told Boston radio station WEEI that “it’s almost embarrassing that LeBron would complain about officiating.”

Riley was clearly irked, calling Ainge “the biggest whiner going when he was a player.”

The Heat and Celtics play April 12 in Miami.

Nuggets’ Lawson injured

Nuggets point guard Ty Lawson missed Denver’s game against the Brooklyn Nets with a strained heel and a plantar fascia tear in his right foot.

An exam Thursday revealed the tear and the Nuggets said surgery is not needed. The team said Lawson is day to day and would not play against the Nets on Friday night.

Lawson injured his heel against Oklahoma City on March 19. He missed the next three games before returning in Wednesday’s loss at San Antonio. Lawson played more than 19 minutes — just seven after halftime — and scored two points.

Lawson leads Denver in scoring at 16.7 points and assists with 6.9 per game.

Clippers retain Wayns

The Los Angeles Clippers have signed guard Maalik Wayns for the rest of the season.

The Clippers announced the deal Friday for Wayns, an undrafted rookie from Villanova.

Wayns has appeared in three games for Los Angeles, averaging 3.7 points and 2.3 assists. The Clippers signed him from the Rio Grande Valley Vipers of the D-League on March 9.

Bulls sign Thomas again

The Chicago Bulls signed forward Malcolm Thomas to another 10-day contract Friday.

Thomas has appeared in one game for Chicago, and had three points and five rebounds in five games with the Golden State Warriors. He also appeared in two NBA Development League games this season with the Santa Cruz Warriors and with the Los Angeles D-Fenders.

He started the season with the Philadelphia 76ers, appearing in 21 games.
