DES MOINES, Iowa (AP) - Iowa State coach Greg McDermott says senior Marquis Gilstrap won't return next season after the school's request for an extra year of eligibility was denied.

The 22-year-old Gilstrap began an injury-plagued career in junior college five years ago. Iowa State had appealed to the NCAA to give Gilstrap one more season under the medical hardship rule.

McDermott announced the NCAA's ruling shortly after the Cyclones lost to Texas 82-75 in the Big 12 tournament Wednesday night.

Gilstrap was the only Big 12 player to average at least 10 points and 10 rebounds in conference games. He scored 17 points and grabbed eight rebounds in the loss to the Longhorns.
