MINNEAPOLIS (AP) -- The Big Ten season hadn't even started yet, and Michigan coach John Beilein was already faced with life without star big man Mitch McGary.
Then he watched Glenn Robinson III go down early in the first half of the conference opener against Minnesota, and suddenly things looked even more bleak. That's when Jon Horford stepped in and delivered a performance that would make his big brother proud to help the Wolverines to a stirring victory.
Horford scored a career-high 14 points and grabbed nine rebounds to help Michigan withstand Robinson's loss and beat Minnesota 63-60 on Thursday night.
"It's always 'next man up' and we have parts that we can put in to the machine," said Horford, the younger brother of Atlanta Hawks versatile big man Al Horford. "Put them in, keep it running."
Zak Irvin scored 15 points on five 3-pointers for the Wolverines (9-4, 1-0), who lost Robinson to an injured left ankle. McGary is out indefinitely after having surgery on his lower back.
The severity or nature of Robinson's injury is still unknown, as is his status for the game on Sunday against Northwestern.
"We've got a lot of work to do to get him ready for Sunday," Beilein said.

Bowling Green (6-7) drew to within a point on a Josh Gomez jumper to make it 44-43 with 10:43 left but couldn't take the lead, then again closed in with a Jehvon Clarke layup that made it 53-51 with 4:56 to go.
