Oregon receiver Tyrece Gaines, a junior JC transfer, and redshirt freshman receiver Diante Jackson have been declared academically ineligible for 2010, according to the school's official Twitter account, which was confirmed by a school spokesperson.
Neither is expected to remain with the program.
Both were highly touted recruits who didn't play last year.
While it's a hit for the Ducks' depth at the position, all three of last season's top wideouts -- Jeff Maehl, D.J. Davis and Lavasier Tuinei -- are returning.
