Isaiah Thomas still appears to resent the Celtics for trading him five months ago. In an interview with ESPN’s Rachel Nichols that aired on Christmas Day, the point guard says Boston’s medical staff gave him misleading information regarding his hip injury last season. As a result, he says he regrets his decision to play through it during the playoffs.

“If I went back and could do it again, I would’ve sat out the playoffs, because I would’ve been playing right now,” Thomas explains. “I would’ve been 100 percent healthy.”

The Celtics dealt Thomas to the Cavaliers in late August for Kyrie Irving. The deal was held up for nearly on week due to concerns over Thomas’ medicals. Shortly after Thomas arrived in Cleveland, doctors determined his hip injury was more severe than initially believed.

He’s been sidelined for the entire season, and is eyeing an early January return.

“I do wish I had more information. It was never, ‘This could be something that could possibly shut you down for a while,”’ Thomas told Nichols. “Because if that were the case, I definitely wouldn’t have played.”
