Washington State University football player Matt Mullennix has been granted a sixth year of eligibility by the NCAA. Mullennix, a senior defensive end from Spangle, Washington, missed the entire 2006 season after suffering a knee injury prior to the school’s football opener at Auburn. Additionally, Mullennix suffered a season-ending injury early in the 2004 campaign. Following a medical appeal process to receive an additional year, the NCAA approved the request earlier this week, clearing the way for Mullennix’s return.
