Simmons fires in NBA, Celtics lose Walker

Ben Simmons' triple-double has helped Philadelphia beat San Antonio in the NBA

Boston guard Kemba Walker has been diagnosed with concussion-like symptoms and taken to a hospital for further evaluation after colliding with a teammate in the NBA.

Walker and Semi Ojeleye collided late in the second quarter of Boston's game against Denver, with Walker striking Ojeleye's abdomen area head-first and going down on to the court in a heap.

Play was stopped as medical personnel from both teams tended to the star guard who was prone on the floor for several minutes.

A brace was placed around his neck to stabilise the area and he was strapped to a backboard before being placed onto a gurney and wheeled off the court.

Without their star point guard, Boston weren't able to get the win and lost 96-92.

Jamal Murray scored 22 points for Denver, including two clutch free throws with 1.5 seconds remaining, but his thoughts were with Walker after the game.

"That's not something you want to mess around with," Murray said. "Prayers out to him and hopefully he's fine."

On a Friday of 10 NBA games, Ben Simmons registered a triple-double of 10 points, 10 rebounds and 13 assists as Philadelphia handed San Antonio their eighth successive loss.

Patty Mills scored five points to go with three rebounds and four assists in 26 minutes of court time for the Spurs.

The 76ers won their third straight game but San Antonio drop to a 5-11 record and are on the longest skid since head coach Gregg Popovich took over in 1996/97.

In Los Angeles, Kawhi Leonard hit a go-ahead jumper with 15.4 seconds to go, lifting the Clippers to a 122-119 victory over the Houston Rockets.

Lou Williams scored all 26 of his points in the second half and Leonard finished with 24 points and six rebounds, while Paul George had 19 points, eight rebounds and seven assists for the Clippers, who won their fourth in a row.

James Harden had 37 points, 12 assists and eight rebounds for the Rockets, who dropped their second straight after an eight-game winning streak.

Elsewhere, Andre Drummond had 23 points and 15 rebounds, helping Detroit to a 128-103 win over the Atlanta Hawks.

The Pistons led 76-57 at halftime and they reached 100 points with more than five minutes remaining in the third quarter, capitalising on their highest-scoring first half since 1983.

In Oklahoma City, Anthony Davis scored 24 of his 33 points in the second half to help the Los Angeles Lakers beat the Thunder 130-127.

Davis also had 11 rebounds and seven assists, and LeBron James added 23 points and 14 assists. The Lakers have won six in a row to improve the best record in the NBA to 13-2.

Also on Friday, Luka Doncic continued his terrific start to the season and scored 30 points and provided 14 assists in Dallas's 143-101 win over Cleveland.

Other winners on Friday were Washington over Charlotte, Brooklyn over Sacramento, Miami over Chicago and Utah over Golden State.
