Former Grizzlies owner Michael Heisley at Chicago hospital in a coma

Some sad news out of Chicago, where Grizzlies' GM Chris Wallace is reporting that former Griz owner Michael Heisley is currently in a coma at a Chicago hospital.

Heisley, 75, who had suffered a stroke just shortly after the All-Star Break, has had some serious issues with his heart over the last few years. As for the relation between the stroke and the coma, we don't really know many details beyond what Wallace had stated to Chris Vernon.

Heisley owned the Grizzlies for 11 years, before selling the team to Robert Pera and his team of investors this past June.

Our thoughts are with Mr. Heisley and his family.
