Ja Morant had 29 points and nine assists, and the Memphis Grizzlies beat the Boston Celtics 132-126 in overtime on Monday night.

Dillon Brooks added 24 points, seven rebounds and seven assists as the Grizzlies won for the third time in four games. Jonas Valanciunas had 16 points and 19 rebounds.

Jaylen Brown led Boston with 27 points, and Jeff Teague finished with a season-high 26 points. Robert Williams III had 17, and Marcus Smart scored 16.

"We had this one," Brown said, later adding: "It's definitely one we want back. We played hard to get back into the game. There's still a lot of stuff we've got the clean up."

Morant scored the last three points of the game from the free-throw line. Brooks had five points early in the extra period.

"Credit our guys," Memphis coach Taylor Jenkins said. "Big stops and big rebounds down the stretch to close out a big win."

Morant added: "Us continuing to fight and be able to lock in late in the game, won us this game."

The Celtics already were without starting guard Kemba Walker when Jayson Tatum was a late scratch with an illness. That meant two of Boston's top three scorers were missing.

"When you are missing guys like Jayson and Kemba, you have to win with a better defense," Celtics coach Brad Stevens said. "I think that's what we've been able to do in the past."

But this time, they were not able to overcome Memphis, which played well in the extra period. While Morant and Brooks led the offensive attack, Stevens pointed to Valanciunas as a major factor. He said the Grizzlies center "just destroyed us."

"Even though he ended with 16 points, it felt like a lot bigger than that," Stevens said. "It felt like he was getting what he wanted off the glass."

Boston trailed by nine midway through the fourth quarter. But Smart found Daniel Theis for a tying alley-oop dunk with 7.3 seconds left in regulation, sending it to overtime.

Brown, who connected on 10 of 18 from 3-point range en route to 34 points in a win over Orlando on Sunday, struggled through much of three quarters, starting 3 of 11 from the field. He finished 11 of 24.

"We played together. We were connected out there," Brooks said. "We had minor slippage, but we found a way to overpass it and make the right plays to win the game."

The Celtics have lost six straight on the second night of back-to-backs, many of those without Walker.

"We started the year off great on the second night of back-to-backs, and have not been good the past month," Stevens said, later adding: "The formula doesn't change just because you played yesterday. You have to have the ability for guys that are fresh to impact the game."
