BOSTON — When the trade deadline loomed and the rumors overtook the NBA, all Tristan Thompson could do was sit at home. Thompson said he had contracted COVID-19, which he said was no joke, that forced him to miss 13 games dating back to March 14.There were reports the Celtics were shopping him in the trade market. But there was also a rumor Thompson was reportedly “not loved in (the Celtics’) locker room.” The comments were made on The Ringer’s Mismatch podcast, where Kevin O’Connor and Chris Vernon talked about Boston’s season-long struggles.Thompson is back on the court and out of quarantine. He helped boost the Celtics to a 101-99 win over the Knicks on Wednesday at the TD Garden. He had a chance to address the rumors, adding all he could do was “laugh” once he heard about them.“In my 10 years of basketball, I don’t think there’s one teammate that doesn’t like me in the locker room,” Thompson said. “So, I knew that was full of shit.”The Celtics were quick to back up Thompson once the rumors swirled. Jaylen Brown and Kemba Walker both took to Twitter. C’s coach Brad Stevens backed up the veteran forward as well when asked about the report.Brown tweeted a cap emoji, meaning the rumors weren’t true. Walker — who rarely tweets, as Thompson pointed out — said “we love TT” in his short message.“It was (O’Connor) just trying to get some clickbaits on my name,” Thompson said. “But I’m used to it. Why not mention my name? Especially with our team going through an up-and-down season like everyone is trying to say. So it makes sense to point out one of the better guys.”Thompson signed with the Celtics on a two-year contract after spending the first nine years of his career in Cleveland, where he won a championship. He had a slow start to the season, but had been playing well recently until his stint with the coronavirus. Thompson is averaging 7.9 points and 8.4 rebounds per game this season.While he was on a minutes restriction, Thompson was solid Wednesday, putting up seven points, eight rebounds and three blocks. He was a team-high plus-24 in 22 minutes, and Stevens noted his physicality gave them a big boost inside. That was a huge help against a team like the Knicks, who are more than willing to make it a grind-it-out, tough contest.With Thompson back, he should help shore up the center depth alongside Robert Williams III. Thompson said he couldn’t be brought down by the negative reports.“That was a joke, and you can ask any of my teammates from 2011 I’ve played in the NBA until now, and I don’t think there’s one teammate that doesn’t like me,” Thompson said. “Even a trainer, equipment guy, ball boy. I’ve got a pretty good rapport in this league. So I’m not going to let some guy with Twitter fingers try to bring down what I’ve built.”
