BOSTON — The Boston Celtics may soon have one of their top players back on the court.

All-Star point guard Kemba Walker has been cleared to begin practicing, the team announced Friday.

Walker hasn’t played this season after receiving a stem cell injection in his left knee prior to the start of training camp last month.

He’s been on a 12-week strengthening program since the early October procedure. Walker injured his knee prior to the resumption of last season in the Florida bubble, but returned to play during the playoffs.

Coach Brad Stevens said Walker has been pain-free while going through individual workouts with the coaching staff. Stevens said the next step is for him to go through some live practices with teammates.

“I don’t think he’s too far. He looks great. He feels great,” Stevens said. “Probably the best he’s felt since he’s been here. … Hopefully he’ll be back soon, but we’re not gonna rush that.”

Walker was a big part of Boston’s run to the Eastern Conference finals in the bubble, averaging 19.6 points and 5.1 assists during the postseason. The Celtics lost the series in six games to Miami.

76ERS: The team was quarantining in New York on Friday because of a positive COVID-19 test for guard Seth Curry.

A person familiar with the situation says the Sixers stayed overnight after the team learned of Curry’s positive result during Thursday’s loss against the Nets. The person spoke to The Associated Press Friday on condition of anonymity because the team has not made Curry’s condition public. The person said as of Friday morning, Curry was the only positive test on the Sixers.

Curry sat out Thursday’s game because of a sore left ankle and appeared to wear a mask as he sat on the bench for part of the first half.

The Sixers are scheduled to play Denver in Philadelphia on Saturday.

The 76ers announced Thursday night that they would not hold practice Friday. Typically, players must remain quarantined for a period of seven days if they have had direct contact with someone who tested positive.
