Kofi Kingston says that's entirely possible for Lamar Jackson ... telling TMZ Sports after watching the Ravens star flip during a touchdown run this past Sunday, he could see the QB killin' it in the ring!

"I would love to see what Lamar could do in a wrestling ring," Kofi says. "He would be incredible."

Lamar put his athleticism on full display in Baltimore's huge win over the Chiefs ... somersaulting into the endzone on a key fourth-quarter play.

The 24-year-old didn't exactly stick the landing -- he joked he hurt his backside in the tumble -- but Kofi tells us the sheer athleticism of it all stuck out to him big time.

"I'd give it a 10 out of 10," Kofi said of the flip. "I don't really care about the form ... He was just out there showing off."

And, now, Kofi says he's pretty damn sure Lamar could be as big of a star as he is in Vince McMahon's world!!!

"It'd just be a matter of getting the psychology aspect of putting matches together and stuff like that," Kingston says.
