Robert Swift's attempt to revive his pro basketball career continues.

More than five-and-a-half years after playing his final professional game for the Tokyo Apache, the veteran center is vying to make a comeback in the NBA Development League.

On Sunday, Swift participated in a workout, including a scrimmage, conducted by the D-League's Santa Cruz Warriors. According to the D-League Digest website, 18 players were invited to the workout in Oakland, California.
