Gophers junior forward Jamison Battle, the team's leading returning scorer, underwent minor foot surgery Friday and his status is week-to-week, the team announced.
Battle, who was named Wednesday to the Julius Erving Award preseason top 20 watch list, did not participate in the team's closed scrimmage last Saturday against Colorado State.
Battle's availability for the Nov. 7 opener against Western Michigan is not likely. The Gophers will play without him for the exhibition game Wednesday vs. St. Olaf at Williams Arena.
The 6-7 former DeLaSalle star led the Gophers in scoring (17.5 points per game), rebounding (6.3) and three-point field goals (75) last season after transferring from George Washington.
Gophers second-year coach Ben Johnson praised the work ethic this offseason, as Battle shed nearly 20 pounds to prepare himself to play on the perimeter. Battle was named to the All-Big Ten preseason team earlier this month.
"He's taken that next jump with not only his body," Johnson said earlier, "but now his experience because he's been through it is teaching all of our guys every single day in practice."
Johnson told the Gophers freshmen they needed to take advantage and learn "from a guy who I think has a chance to play at the next level."
Season-ending knee injuries for the second straight year to forwards Parker Fox and Isaiah Ihnen have been a blow to the Gophers' frontcourt depth. They're more equipped to handle injuries in the post this season with North Carolina transfer Dawson Garcia, freshmen Pharrel Payne and Joshua Ola-Joseph, and 7-foot sophomore Treyton Thompson.
