BYU running back LJ Martin out 4-6 weeks with lower-body injury

BYU starting running back LJ Martin will miss four to six weeks after suffering a lower-body injury in the first half of the Cougars' 17-10 win over TCU in Week 5, putting his availability for several key games in doubt. Martin has recorded 44 rushing attempts for 344 yards and three touchdowns through five games, plus five receptions for 41 yards. His absence removes a centerpiece from a BYU offense that relies heavily on its running game, coming less than a year after he produced 1,305 rushing yards and 12 touchdowns. Martin is expected to miss games against Iowa State, Notre Dame, UCF, and Arizona State, with potential absences against Utah and Baylor. The Cougars will turn to Preston Rex, freshman Journee Tonga, and Devaughn Eka, while quarterback Bear Bachmeier may take on a larger rushing role.
