Dan Persa is out for the season after rupturing the Achillies tendon in his right foot in the fourth quarter of Saturday's 21-17 Northwestern victory over Iowa at Ryan Field. Persa had just thrown the winning touchdown pass to Demetrius Fields when he fell to the ground in pain. Coach Pat Fitzgerald said Persa ruptured the tendon while he was jumping to celebrate the catch. Fitzgerald also said Persa will have surgery Saturday night at an undisclosed hospital.
