Thomas had been lingering on the free agent market with few known suitors since his contract expired with the Los Angeles Lakers.
Former Los Angeles Lakers guard Isaiah Thomas has signed a one-year $2.3 million deal with the Denver Nuggets, per ESPN's Adrian Wojnarowski. Last July, Thomas famously told CSN New England that he expected the Celtics to "bring the Brinks truck out."
After opening his National Basketball Association career with the Sacramento Kings in 2011-12 and subsequently playing for the Phoenix Suns, Thomas exploded into stardom with the Boston Celtics.
Thomas, who is a two-time All-Star player, was dealing with a hip injury that eventually required surgery.
He guided the Celtics in the 2017 Eastern Conference finals against the Cleveland Cavaliers before he was sidelined due to the hip ailment.More news: US firms doing business in China mostly oppose tariffs, survey shows
After just two months of action, Thomas was dealt to the Lakers at the trade deadline.
Maybe these posts had an effect as it was reported soon after that he had signed a one-year deal with the Denver Nuggets. In 15 games with the Cavs last season, Thomas averaged 14.7 points and 4.5 assists per game, before he was dealt to the Los Angeles Lakers at the National Basketball Association trade deadline.
But it was in Cleveland that Thomas proved to be a horrendous fit with LeBron James.
According to ESPN, Thomas will have a key role as an off-the-bench scorer.
Malone had been Thomas' coach during the 2013-14 season in Sacramento, two teams removed from the guard's arrival in Boston.
