The 26-year-old is the son of Jazz legend John Stockton. He has appeared in three games for Utah this year, scoring 10 points and going 2-of-3 from beyond the arc in nine total minutes.
Stockton spent the bulk of this season in the NBA G League. He was averaging 16.3 points and 5.2 assists in 39 games for the Reno Bighorns, the Sacramento Kings' G League affiliate, before the Jazz signed him to a 10-day contract in March.
Utah has three games remaining in the regular season. While the Jazz have all but qualified for the playoffs—two games separate them from the ninth-place Denver Nuggets—they're still looking to secure home-court advantage in the first round. Utah is in fourth place and one game ahead of the San Antonio Spurs.
