BOSTON — The Boston Celtics said point guard Kyrie Irving will miss three to six weeks after surgery on his left knee.

Irving had a “minimally invasive” procedure to remove a wire that had been placed in his knee during surgery to repair his broken kneecap from the 2015 NBA finals. The team said Saturday that Irving’s kneecap is fully healed and structurally sound, but the tension wire was irritating his tendon.

The Celtics have the second-best record in the Eastern Conference. The playoffs begin April 14 – three weeks away. The longer estimate for his return means Irving would not be able to come back until the second round.

If Irving needs six weeks, that would mean the Celtics – a team that has been dealing with injury issues since the first quarter of the first game of the season, when Gordon Hayward was lost for the year – would need to get through the entire first round without their best player.

“It’s tough when you lose anybody, especially multiple guys,” Boston’s Jayson Tatum told Celtics.com. “We’re just going to have to try to figure it out and figure out how to win games.”

WARRIORS: Stephen Curry suffered a Grade 2 sprain of his left MCL on Friday night.

The Warriors said Curry will be evaluated again in three weeks.

“It could be a lot worse,” Warriors Coach Steve Kerr told reporters just before Curry’s MRI results were revealed. “You think about some of the other guys in the league that have suffered injuries this year. Gordon Hayward is the first one that comes to mind. This is not a major injury. The timing’s not ideal but we can overcome this.

“Steph can be back this year. … Just got to hold down the fort and understand this is all part of the journey.”

The Blazers led by as many as 12 points in the third quarter, but rookie Jayson Tatum’s layup and Morris’ 3-pointer gave the Celtics a 101-96 lead with 54.8 seconds to go, and Tatum’s dunk extended the lead to 103-98.
