The Denver Nuggets will tender center Timofey Mozgov a $3.9 million qualifying offer by the June 30 deadline, according to a source.

The decision will make Mozgov a restricted free agent. Denver will be in position to match any offer sheet signed by the center in order to retain his services.

The source said, "Mozgov is a priority and it will take a lot [for Denver] not to match."

Mozgov is currently Denver's third center, behind Kosta Koufos and JaVale McGee. Koufos and McGee both have guaranteed contracts for the 2013-14 season.
