BYU running back LJ Martin is expected to be sidelined for about a month after suffering a lower-body injury during the Cougars’ win over TCU. Multiple outlets report he has exited the game and is now facing an extended absence.

The reports estimate a timetable of roughly four to six weeks, which would rule him out of upcoming games. CBS Sports specifically notes BYU will miss Martin in an Oct. 17 top-10 matchup against Notre Dame, while additional updates indicate he is also expected to miss the game versus Iowa State. One outlet describes Martin as the reigning 2025 Big 12 offensive player of the year, underscoring the impact of his injury on BYU’s offense.

Across the coverage, the common themes are the injury’s timing (in the TCU game), its classification as lower-body, and the consistent expectation of a multi-week recovery period.
