In today's game where the Bucks fell to the Cavaliers, Giannis suffered a groin strain. After the game, head coach Doc Rivers indicated the situation doesn't look promising.

Doc Rivers said: "Giannis will undergo an MRI on Tuesday, but he was already dealing with the injury in the first quarter of today's game."

"We don't know the specifics yet, but it doesn't look good... We have a lot of work to do—either find suitable replacements or try some tactics that might pay off later."

Following today's loss, the Bucks sit eighth in the Eastern Conference with an 8-7 record.
