Joe Jackson, an undrafted point guard out of the University of Memphis, is finalizing a free-agent contract with the Phoenix Suns, a league source told RealGM.

Jackson, 22, averaged 14.1 points, 4.5 assists and 3.6 rebounds in his senior year a season ago.

Despite going unselected in the June NBA draft, Jackson received interest as a second-round pick and then accepted an invitation to the Memphis Grizzlies’ summer league entry. The swift, 6-foot product averaged 5.5 points on 46.2 percent shooting in four summer league games.
