BYU football lost two stars to injury in the first half of Saturday’s game against TCU.
Running back LJ Martin left with an apparent lower-body injury, and linebacker Isaiah Glasker exited after taking a hit during an interception return.
Both players were ruled out at halftime, according to ESPN.
Martin, the 2025 Big 12 Offensive Player of the Year, walked gingerly off the field in the first half and went into the blue medical tent. He later re-emerged before returning to the tent with BYU’s athletic trainers.
He was on the sideline wearing his helmet but never got the go-ahead to return to the game. Martin has been BYU’s leading rusher this season with 42 carries for 328 rushing yards and three touchdowns.
He had just two carries for 16 yards in the game before leaving with his injury. Martin has dealt with injuries in past seasons, including a shoulder dislocation that required surgery.
