Thomas, who was upgraded to questionable for the Nuggets’ game against Sacramento in Denver, made his decision to play on Wednesday morning.
Thomas practiced 5-on-5 on Tuesday and participated in a shootaround Wednesday morning before deciding to play. Thomas, 29, would be returning to a Nuggets team (38-15) that is within 2½ games game of first-place Golden State in the West and is employing a bevy of talented guards, including Jamal Murray, Gary Harris, Malik Beasley, Will Barton and Monte Morris.
Thomas averaged 28.9 points per game for the Boston Celtics in 2016-17, a second-team All-NBA season that appeared to be clearing the way for a long-term, $100 million contract.
But an injury on the same right hip that cut short his playoffs in 2017 and cost him eight months of rehab, and a trade to the Cleveland Cavaliers that summer, upended his hopes for that kind of long-term deal.
Thomas joined the Los Angeles Lakers as part of a trade-deadline deal with Cleveland, where he had played only 15 games in 2017-18.
