Reginald Shon Jackson is an American professional basketball player for the Detroit Pistons of the National Basketball Association (NBA).

​

Jackson was assigned multiple times to the Tulsa 66ers of the NBA Development League between March and December 2012.

​

As a sophomore during the 2012–13 season, Jackson's minutes and production steadily increased. In Game 2 of the Thunder's first round playoff series against the Houston Rockets, starting point guard Russell Westbrook tore his meniscus and was ruled out for the rest of the season, as Jackson was promoted to a starting role. In his first career start, he had 14 points, 2 rebounds and 1 assist, helping the Thunder win Game 3. As a starter during the playoffs, Jackson averaged 15.3 points, 5.3 rebounds and 4.7 assists per game.

​

On February 6, 2014, Jackson was chosen to compete in the 2014 Taco Bell Skills Challenge. On April 26, 2014, he recorded a career-high 32 points along with 9 rebounds against the Memphis Grizzlies in Game 4 of the 2014 NBA Playoffs first round series, which the Thunder won 92–89. Jackson had 5 points in the final minute of regulation to force overtime, but heaved a shot from full court, still with 4 seconds left. In overtime, Jackson hit four free throws to ensure a Thunder victory. He was praised for his performance as the Thunder's star players Kevin Durant and Russell Westbrook had off shooting nights.

​

On November 11, 2014, Jackson scored a season-high 29 points on 12-of-21 shooting in the 78–85 loss to the Milwaukee Bucks.

​

On February 19, 2015, Jackson was traded to the Detroit Pistons as part of a three-team deal that also involved the Utah Jazz. Three days later, he made his debut for the Pistons as he recorded 17 points, 5 rebounds and 5 assists in a 106–89 win over the Washington Wizards. On March 17, Jackson recorded 23 points and a career-high 20 assists in a 105–95 win over the Memphis Grizzlies. On March 27, Jackson recorded his second career triple-double just ten days later. Jackson finished the game with 26 points, 11 rebounds and ten assists in a 111–97 win over the Orlando Magic. Jackson became the first Pistons guard to record multiple triple-doubles in a season since Isiah Thomas during the 1986–87 season, and the first Pistons player to do so since Grant Hill during the 1997–98 season.

Considered a three-star recruit by Rivals.com, Jackson was listed as the No. 29 shooting guard and the No. 115 player in the nation in 2008. Source.
