With 10:29 remaining in the second quarter on Sunday night, Harrison Barnes was elbowed in the face by Pelicans forward Dante Cunningham.
The Warriors' small forward left the game and went to the locker room to get stitches for what the team called a "mouth laceration."
Barnes started the second half but didn't score again.
Following the win on Sunday, Draymond Green didn't hold back.
"Seemed like a couple cheap ones to me," Green said. "But it is what it is, you know ... I guess he (Cunningham) is supposed to be their tough guy or whatever it is.
"The same guy elbowed two guys in the nose. That's not a coincidence."
Green told the Bay Area News Group that he took an elbow or a forearm from Cunningham late in the first half, and is still sore.
Head coach Steve Kerr also voiced his displeasure.
“I didn’t think either play was warranted, let’s put it that way,” Kerr said. "There’s a difference between physical play and clubbing somebody across the face a couple of times.”
On Monday, the Warriors announced that Barnes sustained a nasal fracture and is questionable for Tuesday night's game in Memphis.
Kerr told BANG that if Barnes plays, he expects him to wear a mask.
