Brigham Young's McKay Jacobson (6) hauls in a catch under pressure from Florida State's Patrick Robinson (21) last month.

PROVO — BYU wide receiver McKay Jacobson will be sidelined for 4 to 6 weeks with a pulled hamstring, coach Bronco Mendenhall announced Monday morning.

Jacobson, who has caught 11 passes for 280 yards and three touchdowns this season, suffered the injury during warm-ups prior to last Friday night's 35-17 win over Utah State and he did not play against the Aggies. The injury was originally reported as tightness in the hamstring, but an MRI performed over the weekend revealed the hamstring pull. Mendenhall said the pull was "way up high at the origin part of the muscle."

The injury occurred while Jacobson was stretching and Mendenhall called that "pretty rare."

With Jacobson out, true freshman Brett Thompson is expected to see more playing time in a rotation that features Luke Ashworth, O'Neill Chambers and Spencer Hafoka.
