The Denver Nuggets have promoted assistant general manager Arturas Karnisovas to the role of general manager, a source confirmed to ESPN's Brian Windhorst.
Karnisovas reportedly was a finalist for the vacant GM position with the Milwaukee Bucks.
Tim Connelly, who had been the team's GM, will take on a new role of president of basketball operations for the Nuggets, the source confirmed to Windhorst.
Both Karnisovas and Connelly began their Nuggets careers in 2013.
The 46-year-old Karnisovas has been Denver's assistant GM since '13. This past season, he also served as the team's vice president of basketball operations.
Before joining the Nuggets' front office, he worked five seasons for the Rockets, including as their director of scouting.
Karnisovas played at Seton Hall, won Olympic bronze medals for Lithuania in 1992 and '96, and played several years internationally.
The Denver Post and The Vertical earlier reported the front-office moves.
