the rest of the 2006–07 NBA season, but returned ahead of schedule to start the 2007–08 NBA season. His 2007–08 season was a disappointment, as his injury disrupted his play and confidence on the court and he was largely a liability. Krstić later stated in his blog that he felt he let the team down, and vowed to return to his old form at the start of the 08–09 season. Triumph Lyubertsy During the 2008 summer off-season, Krstić entered negotiations with the Russian Super League team Triumph Lyubertsy and eventually signed a 2-year contract (with the NBA an opt-out option) worth €6 million euros net income with them on July 29, 2008. He averaged 10.4 points and 5.1 rebounds per game in seven games in the Russian Super League and 13.3 points and 7.3 rebounds per game in 6 games in the EuroChallenge. Oklahoma City Thunder On December 19, 2008, two NBA league sources told ESPN.com that the Oklahoma City Thunder had agreed in principle to sign Krstić to a three-year offer sheet. On December 22, Krstić officially signed the offer sheet. The New Jersey Nets had seven days to match the offer, or Krstić would be free to join the Thunder.

He played for the first time in a Thunder uniform on January 7, 2009, versus the Minnesota Timberwolves, scoring six points and blocking 2 shots in 16 minutes. Boston Celtics On February 24, 2011, Krstić was traded along with Jeff Green and a 2012 first round pick to the Boston Celtics for Kendrick Perkins and Nate Robinson.

Krstić's final NBA game was on May 11th, 2011 in Game 5 of the Eastern Conference Semifinals against the Miami Heat. Boston would lose that game 87 - 97 (thus losing the series to Miami 4 - 1) with Krstić recording 8 points, 2 rebounds and 2 blocks. CSKA Moscow On June 22, 2011, Krstić signed a two-year contract with the Russian powerhouse CSKA Moscow. Over the season, he averaged 14.2 points and 5.4 rebounds in 24.5 minutes per game in the Euroleague. That earned him his first selection for the All-Euroleague First Team.
