Anthony Davis defended Los Angeles Lakers team-mate LeBron James after his ejection in the wild win over the Detroit Pistons, insisting the NBA superstar is not a "dirty dog".

James was ejected for an elbow to Pistons center Isaiah Stewart's eye, which was deemed a flagrant 2 foul, with the incident setting off a wild brawl in the Lakers' rallying 121-116 victory.

Stewart, who was also tossed from the game, was left bloodied from his right eye and incensed, repeatedly attempting to charge at James, having to be restrained and escorted off the court by coaches and team-mates amid chaotic scenes.

James and Stewart had jostled for position for a rebound from Jerami Grant's free throw early in the third quarter, when the four-time MVP's left elbow struck the Pistons big man's eye.

"Everyone in the league knows LeBron's not a dirty guy," said Davis, led the Lakers' comeback with 30 points, 10 rebounds, six assists, five blocks and four steals. "As soon as he did it, he looked back at him and said 'my bad, I ain't try to do it'.

"I don't know what [Stewart] was trying to do. I know nobody on our team, one through to 15, was having it. We wanted to protect our brother.

"I've never in 10 years seen a player try to do that... It was uncalled for. You got a cut above your eye, accidental, it wasn't on purpose.

"We weren't going to allow him to keep charging our brother like that. I don’t know what he was trying to do. We just wanted to get the win for him."

The Lakers were trailing by 12 points at the time of the incident but went on to win behind Davis' big performance on the road.

Davis became the first Laker with a 30/10/5/3/5 game since Hall of Famer Shaquille O'Neal in 2001.

Russell Westbrook (26 points, 10 assists and nine rebounds) was important down the stretch too, with 15 points, five rebounds and six assists in the fourth quarter alone, as the Lakers dominated with a 37-17 final quarter.

Amid the chaos of the brawl, Westbrook received a technical foul which left him dumb-founded post-game, stating he was an easy target for the referees.

"I didn't know I had a tech… woah, that's interesting," Westbrook told reporters. "For being Russell, I guess? I don’t know why but whatever.

"They had to put it on somebody. I'm an easy person to put s*** on. Why not me?"

Lakers head coach Frank Vogel hailed his side's response to the incident, reeling in the Pistons' game-high 17-point lead to claim a win that helped the championship-chasing franchise improve to 9-9 for the season.

"To me, it's one of those things that can change the momentum of your season," Vogel said. "To see guys rally around a team-mate that just got ejected like that in a strange circumstance.

"We played with incredible guts, started the fourth quarter down by 15. That's the determination that this team is going to need. That's how hard we've got to play to get Ws. "That's a heck of a win for us."
