10:33pm: The move is official, the Bulls confirmed in a press release.
4:36pm: To open a roster spot for the addition of Tristan Thompson, the Bulls will waive forward Alfonzo McKinnie, tweets Shams Charania of The Athletic.
McKinnie earned a standard contract with Chicago after signing a pair of 10-day hardship deals with the team in December. He appeared in 17 games, made three starts and averaged 3.5 points and 1.9 rebounds in 12.1 minutes per night.
Because his release will come before March 1, McKinnie will be eligible for the playoffs if he signs with another team. The 29-year-old has played for five teams in his five-year NBA career, starting with the Raptors in 2017/18 and spending time with the Warriors, Cavaliers and Lakers as well.
Thompson is expected to officially join the Bulls soon after completing a buyout with the Pacers earlier this week.
