Patterson, from Ringwood, Okla., appeared in 14 games during the 2007-08 season, his true freshman year at CU. While he played in nine non-conference games, the lanky big-man saw action in only five Big 12 contests.
He averaged 1.4 points and 1.4 rebounds.
Patterson will remain on scholarship at CU through the end of the current semester, Rodger Patterson said. He hopes to find a school at which to play by the end of the month and enroll by June. He'll have to sit out a transfer year, per NCAA rules, but can use a redshirt season.
Patterson has been in contact with several schools about the possibility of transferring, his father said. Included on that list are Wichita State, Missouri State, Central Arkansas, North Texas, UT-Arlington and Northern Illinois.
Meanwhile, Xavier Silas, who was dismissed from the Colorado team by head coach Jeff Bzdelik with five games remaining in the Buffs' Big 12 schedule this past season, will transfer to Northern Illinois. Silas was in good academic and legal standing, and did not violate any team rules, when he was released from the CU team.
At NIU, Silas, the 6-5 guard, will be playing under Ricardo Patton, the coach who originally recruited him to Colorado.
Patterson's departure means only four of the players Patton recruited to CU remain on the roster for next season, including sophomore Levi Knutson, sophomore Jeremy Williams, junior Dwight Thorne and senior Jermyl Jackson-Wilson.
It appears CU now has three scholarships to give in the current signing period. One prospect who has visited CU, Wesley Witherspoon, has said he will announce his decision May 1.
