University of Louisville freshman Quinn Slazinski was not in attendance at the program's annual Tip-off luncheon on Wednesday afternoon, but instead at a local hospital.

"He's in the hospital with appendicitis," Mack confirmed to the media at the event. "About two hours ago I thought he was having surgery and now antibiotics might allow him not to. We're going to know in 24 hours if he's going to have surgery or not."

A member of Louisville's highly-rated, six-man 2019 recruiting class, there has been discussion of possibly redshirting Slazinski. However, the impact of the medical surprise won't have any bearing on Mack's decision to redshirt the 6-foot-8 forward newcomer or not.

"That's really independent of the redshirt talk because even if he has surgery you're talking about him being out a week," Mack said, also adding that he'll wait "until the last possible second" before making a final decision on playing status for this season.

A product of Huntington (W.V.) Prep, Slazinski was a three-star prospect that signed with Louisville over scholarship offers from DePaul, Georgia Tech, Houston, TCU, Texas, Wake Forest and others.
