Michigan may have to open the 2018 season without one of its top wide receivers.

Sunday afternoon, Angelique Chengelis of the Detroit News reported that wide receiver Tarik Black sustained an injury during practice on Saturday. The injury was reportedly to his right foot.

According to Chengelis, Michigan says there is no definitive time frame for Black to return.

Black played in just three games for the Wolverines in 2017, catching 11 passes for 149 yards and a touchdown. He suffered a season-ending injury to his left foot last fall.

Heading into the season, Black was expected to be one of the best receivers on Michigan’s and potentially one of the top in the B1G.

Michigan opens the season on Saturday as it travels to South Bend to battle Notre Dame. It’ll be the first meeting between the two programs since 2014.
