Martin (ankle) is considered doubtful to face Iowa State on Friday night, per Jay Drew of Deseret News.
Analysis:Martin was knocked out of BYU's tilt with TCU in Week 5, and he's now considered doubtful for Week 6 against Iowa State. The tailback still has a slim chance to play, but at this juncture, expect plenty of carries for Preston Rex in the Cougars' backfield Friday night against the Cyclones.
