Corliss Williamson is set to retire from the NBA and become an assistant coach at Arkansas Baptist College, the school's athletic director said Tuesday.

Williamson, who led Arkansas to the 1994 national championship, has played 12 pro seasons with Sacramento, Toronto, Detroit and Philadelphia. He was on the Pistons when they won the 2004 NBA title.

Williamson averaged 9.1 points in 68 games last season with Sacramento.
