Mitch McGary's back issue remains a bit of a mystery.
Michigan coach John Beilein said his sophomore big man is making good progress but remains day to day, with the season opener still a couple weeks away. Beilein announced last month that McGary had been limited because of a lower back condition.
"We're super-cautious. He's been doing these underwater treadmill workouts that are really productive. I know I couldn't do some of those," Beilein said Thursday. "If he keeps making this progress, day after day it's still day to day one of these days he's going to have to get out there and see what he can do."
The 6-foot-10 McGary averaged 7.5 points per game last season as a freshman, but in the NCAA Tournament he averaged 14.3 points and 10.7 rebounds, helping the Wolverines reach the national championship game, which they lost to Louisville.
If he's at full strength, Michigan should again be one of the top teams in the Big Ten.
"Right now I'm day to day doing stuff on the court, light shooting, limited in what I can do, what they're allowing me to do," McGary said. "There's no target date or anything."
A&M's Roberson has heart procedure
Texas A&M player Kourtney Roberson underwent a procedure at a hospital after experiencing a rapid heart rate during practice.
The school said in a news release that Roberson underwent an outpatient procedure Thursday in College Station, Texas.
The team says the junior from Arcadia, La., is expected to resume basketball activities in "the coming weeks." Roberson had the procedure after he was evaluated by the team's medical staff when the issue arose in practice Monday.
The 6-foot-9 forward averaged 6.9 points and 6.6 rebounds last season, starting 32 of 33 games.
