The Ducks (7-1) will take on the Broncos (6-4) at 4 p.m. Pacific on CBS Sports Network.
Bell broke his foot in May and has missed the season's first eight games. The Long Beach, California product stands 6-9 and weighs 225 pounds. He started most of last season and finished with the second-highest field goal percentage in UO single-season history at 59.7 percent.
Bell is already Oregon's career leader in NCAA Tournament blocks with eight, and set a school record last season with 94 blocks in total. With the Ducks facing lots of injuries this season, his return should be a nice boost.
