Parker played 19 minutes in Saturday's 110-102 defeat to the Jazz. It was his first appearance for the Bulls since Jan. 4 and only his second game since Dec. 13.
The Athletic's Darnell Mayberry wrote Chicago may have viewed the occasion as a chance to give Utah a firsthand look at Parker: "I'm not big on conspiracies, but, man, this felt like the Bulls tried to show Utah what Parker can do. The trade deadline is just a little more than three weeks away, and Utah has long been rumored to have interest in Parker."
ESPN.com's Malika Andrews reported in mid-December the Bulls planned on dropping Parker from the rotation, and the Chicago Tribune's K.C. Johnson noted the team had "engaged in talks with several teams" about trading Parker.
According to Johnson, interested suitors are asking the Bulls to absorb big, multiyear contracts in return for the fifth-year forward.
While both Parker and the Bulls probably want to go in different directions, his deal will make it hard to piece together a trade. He's making $20 million this season and has a $20 million team option for 2019-20, per Spotrac.
Mayberry noted the Jazz in particular might be a difficult trade partner because of the finances. Utah is already $11.5 million over the salary cap, and the team traded Alec Burks ($11.3 million expiring contract) and two second-round draft picks to the Cleveland Cavaliers for Kyle Korver.
Because of those factors, the Jazz will have a hard time putting together salaries to equal the money Parker would add to their payroll.
