The desert hasn't been good to defensive backs of late.
Arizona lost starting cornerback Jonathan McKnight for the season after it was announced he tore his ACL during Wednesday's practice. The true sophomore, brother to former USC tailback Joe McKnight, has a redshirt year available.
That's not a total disaster because McKnight was one of three good cornerbacks, but his injury makes Shaquille Richardson and Trevin Wade the starters with little margin for error, and bumps true freshman Cortez Johnson up the depth chart. Redshirt freshman Jourdon Grandon becomes the nickelback.
McKnight is the third member of the Wildcats' defense to suffer a knee injury this offseason: Safety Adam Hall and linebacker Jake Fischer were hurt in the spring. Hall and Fischer could return to action in October.
Up I-10 in Tempe, Arizona State also has struggled with injuries, most notably cornerback Omar Bolden and linebacker Brandon Magee.
