Chicago Bulls power forward Lauri Markkanen has been shut down for the rest of the season due to a rapid heart rate.

Markkanen did work out on Friday at the Advocate Center with a heart monitor on.

The Bulls' stretch forward, however, says he wasn't really worried about his condition at any point in the last few days and just felt weird.

“I wasn’t really worried at any point,” Markkanen said, via Joe Cowley of the Chicago Sun-Times. “I just kind of felt really weird and just kind of how normally (feel) after a workout … Wasn’t really worried at any point. It wasn’t scary, but felt pretty weird.

“Everything I’ve gotten so far is everything’s good. We’re monitoring me when I’m working out, so it’s safe. We’re trying to get some additional information, but everything’s fine as of now.”

The Bulls will do more testing on Lauri Markkanen next week. Chicago has six games left in the season.
