Golden State's Stephen Curry injured his foot late in Game 3 of the NBA Finals on Wednesday but said he does not expect to miss Friday's contest.

Celtics forward Al Horford ended up on top of Curry during a scramble for a loose ball in the fourth quarter, leaving the Warriors guard writhing in pain on the floor, but he was able to keep playing.

"Obviously will be in some pain, but I'll be alright," Curry said after the game, a 116-100 Celtics win that put Boston up 2-1 in the best-of-seven series. "See how I feel tomorrow and get ready for Friday.

"I don't feel like I'll miss a game. I'll take advantage of these next 48 hours to get ready."

Warriors enforcer Draymond Green picked up a foul for hauling Horford off Curry during the clash.

"I saw him getting dove on and that was about that," Green said. "So I picked up my foul pushing him off him, because he's screaming at the bottom of the pile."

Curry said the injury was similar to, but not as bad as, the foot strain he suffered in a game against the Celtics in March, an injury that kept him sidelined for a month.

Warriors coach Steve Kerr said he removed Curry from the game once it was clear Boston was assured of winning.

"The injury didn't force him out of the game," Kerr told reporters. "I took him out down 14 with two minutes left because we weren't going to catch up. We'll know more tomorrow."

The three-time NBA champion scored a game-high 31 points on Wednesday and called Game 4 a "must win."

"We still feel like we can win the series," he said. "Got to come out with the right intensity and focus in Game 4."

Curry's teammates did not sugarcoat what it would mean if they had to play without him.

"We need him if we want to win this thing," Klay Thompson said.

"He's our identity."
