There is optimism Mitchell Robinson will be ready to go for the Finals.

He underwent surgery on his broken right pinky finger and the hope is that he will be ready for Game 1 on Wednesday, per league sources, though there is still no concrete timeline for him.

It was a “minor procedure,” per league sources. He did not practice Friday, but coach Mike Brown and the Knicks didn’t specify when Robinson had the surgery. They did reveal that the injury did not occur in a game or practice.

“For me, it’s the same — I don’t want to know, just let me know if he can play,” Brown said, “and when he can play. Just like we normally would, we’re getting everybody else ready to go.”

Brown was noncommittal about Robinson’s availability for Game 1. But the fact that the injury is a broken bone rather than a torn ligament in the pinky bodes better for his chances to play through it and still be effective.

“That’s helpful,” Dr. Daniel Kaplan, a sports orthopedic surgeon at NYU Langone health, told The Post. “The reason that’s helpful is that bones are obviously stronger than ligaments. It’s easier to fix a bone and the fixation we can do is gonna be a little bit more stable. If it was a ligament, I would say he’s almost certainly out for the Finals or a longer stretch of time. For a broken bone, depending on the exact nature of it, it might be something that you can much more easily and safely stabilize and get him playing sooner. Broken bone, in this specific setting, is probably a little bit faster of a recovery, or faster to play, at least.

“Fortunately, Mitchell is not a shooter. It doesn’t take a doctor to tell you that. Depending on the nature of the injury and the surgery, it is possible that he can play if they tape his fingers, maybe after like two weeks, would be my guess from the surgery. I’m gonna have to give you a pretty big range. It’s the Finals, they could push it, maybe they can do it as early as one week if they’re being really aggressive. If it was the offseason, it would probably be like six weeks until we would have him start playing.”

No, Robinson is certainly not a shooter. Playing with an injured pinky might not affect him as much as, say, Jalen Brunson, where the pinky is vital for balancing the ball and pushing off his shot. But it can still hinder Robinson where he makes his biggest impact.

“Mitchell is obviously a very physical player, that’s a big part of his game and what he contributes,” Kaplan said. “It’s gonna be a little harder to do things like push someone off if they’re posting up or something like that. Or rebounding, he might be even a little bit more tenuous, it might be harder to grab that loose ball if he doesn’t have that pinky to reach around it.”

Beyond Robinson, the Knicks lack depth at center behind Karl-Anthony Towns. Ariel Hukporti would be the likely next option, but he played sparingly in the regular season and so far in the playoffs. When Robinson missed Game 2 of the second round against the 76ers due to an illness, Hukporti played seven minutes and recorded two points and three rebounds while also picking up four fouls.

Jeremy Sochan is theoretically another option, though he has been relegated to strictly garbage-time minutes since the end of the regular season. The Knicks could utilize small-ball lineups with OG Anunoby at the five, though that will be difficult against either the Thunder or Spurs, both of whom feature star bigs.

If it’s the Spurs, in particular, that the Knicks face in the Finals, Robinson’s availability could be critical. He was excellent when guarding Victor Wembanyama in the Knicks’ NBA Cup final triumph over San Antonio.

“We trust everyone in this locker room,” Towns said Friday. “If this playoff run has shown anything, I feel, to the fans and the media, one through 15 can go out there, put a Knicks jersey on and get the job done. And we truly believe in that. So this is a situation where we’ve garnered enough experience and enough trust in each other that whatever the picture ends up being when we step on that court Wednesday, we feel comfortable.”
