Thomas had been lingering on the free agent market with few known suitors since his contract expired with the Los Angeles Lakers.
Wojnarowski further reports that Thomas' deal with Denver will be for one year at the veteran's minimum.
Isaiah Thomas #7, then of the Los Angeles Lakers, looks to pass the ball during the game against the Orlando Magic at STAPLES Center on March 7, 2017 in Los Angeles, California.
The point guard led the C's to the Eastern Conference Finals and averaged a career-best 28.9 points per game.
Archbishop Welby praises RAF on its centenary
The flypast was wonderful , with over 100 aircraft in the skies: not just historic aircraft, but the aircraft of the future. The RAF has close ties to the royal family, with many of its members, including the Duke of Cambridge serving as pilots.
It is because of that relationship that Thomas, who has said in multiple occasions that he is a starting point guard in this league, is willing to take a sixth man role in hopes to hit the bank in 2019, as the salary cap will expand once more.
That playoff run ended, however, with a hip injury that lingered well past Boston dealing him to Cleveland in exchange for Kyrie Irving.
Hip injuries are tricky, so it's going to be fascinating to see if the surgery Thomas received will completely fix the issues that have hobbled him for the past year. He likely will come off the bench in Denver, where he'll have a chance to be a lead scorer for the second unit, giving the Nuggets a boost when their starters are out.
Originally drafted with the final pick in the 2011 NBA Draft, Thomas has played in 473 NBA games for the Kings, Suns, Celtics, Cavaliers and Lakers. Thomas nearly exclusively came off the bench, scoring 15.6 points per game in 17 games with the Lakers.
