Among the ten was a surprise -- University of Washington running back Chris Polk, who had been characterized by the Huskies and the NCAA as a whole to this point as a junior.
It had been presumed that Polk, who missed all but the first two games of the 2008 season due to injury, had taken a medical redshirt. As it turns out, Polk did not apply for a redshirt and thus, exhausted his eligibility once the Huskies lost to Baylor in the Alamo Bowl.
"We made sure that we followed proper protocol before we invited Chris and that entailed getting everything cleared through the NFL and Coach Sarkisian at the University of Washington," Senior Bowl President and CEO Steve Hale said. "Once it was determined that Chris had exhausted his eligibility at Washington there was no question we wanted him on our roster. He is an excellent player and has a bright future in the National Football League."
Polk was not among the 65 underclassmen granted special eligibility by the NFL for the 2012 draft.
Polk's addition to the Senior Bowl roster is a significant one. Ranked as the No. 4 running back in the 2012 draft class by NFLDraftScout.com, Polk leaves Washington having rushed for 4,049 yards -- the second most in school history behind Napoleon Kaufman, a first round pick by the Raiders in 1995.
Listed by Washington at 5-11, 222 pounds Polk is a surprisingly physical back for his size. Though he lacks elite breakaway speed, his vision, burst and determined running made him the MVP for the Huskies in 2010 over quarterback Jake Locker, drafted No. 8 overall by the Titans in April. Polk finished second behind former Washington running back Corey Dillon for the single-season record with 1,415 rushing yards in 2010. He earned First Team All Pac-12 accolades in 2011 after rushing for even more yardage (1,488), including posting 147 yards and a score against Baylor.
Polk is one of three Washington players to be invited to Mobile for the 2012 Senior Bowl. Joining him will be offensive lineman Senio Kelemete and defensive tackle Alameda Ta'amu.
The remaining seven Pac-12 prospects invited to the Senior Bowl are Arizona quarterback Nick Foles and wide receiver Juron Criner, Arizona State offensive lineman Garth Gerhart and wide receiver Gerell Robinson, California linebacker Mychal Kendricks and offensive lineman Mitchell Schwartz and Utah offensive lineman Tony Bergstrom.
