Los Angeles Lakers point guard Rajon Rondo will be sidelined at least a month after undergoing surgery to repair a ligament on his right ring finger.

Rondo sprained his finger during Los Angeles' Christmas Day victory at Golden State. He missed the Lakers' last-second loss at Sacramento on Thursday night along with LeBron James, who strained his groin against the Warriors.

Rondo had surgery Friday, and he is expected to fully recover in four to five weeks, according to the team.

Rondo is averaging 8.4 points, 6.7 assists and 4.4 rebounds while providing solid leadership in his first season with the Lakers, who signed him as a free agent in July.

But the veteran has appeared in only 14 games because of a three-game suspension for fighting and a 17-game absence after breaking a bone in his right hand, an injury that also required surgery.

He only returned from his broken hand Dec. 21, playing in three games in five days before getting hurt again.

Lonzo Ball is likely to remain the Lakers' starting point guard in Rondo's absence.

The Lakers haven't speculated on how long James will be sidelined. The four-time NBA MVP turns 34 on Sunday.

John Wall rests heel

Washington Wizards point guard John Wall missed Friday night's game at Chicago with a left heel injury and will see a specialist.

Coach Scott Brooks would not speculate on the severity of the injury. He said Wall has managed an issue with his heel for years and "it comes and goes."

Wall is averaging 20.7 points and 8.7 assists per game. He missed a game with an injury to his heel Dec. 10.

Dion Waiters on mend

Dion Waiters is about to take a big step toward returning to the Miami Heat.

The Heat said Friday that they are sending Waiters to the Sioux Falls Skyforce, their G League affiliate. The plan is for Waiters to practice with the Skyforce and return to Miami in time for Sunday's game against Minnesota.

Waiters has been sidelined since Dec. 22, 2017, with a surgically repaired ankle.

For his career, Waiters is a 13.3-point scorer. This is the seventh NBA season for the former Syracuse guard, who played for the Cavaliers from 2012 to 2015.
