Source: Free-agent center Tyler Zeller signing with Spurs for rest of season

Free-agent center Tyler Zeller is signing with the San Antonio Spurs for the rest of the season, a source told ESPN's Adrian Wojnarowski.

Zeller, a six-year veteran, had not played this season. He was in the Nuggets' training camp but was waived in October.

Zeller, 30, has career averages of 7 points and 4.4 rebounds per game.

The Spurs have been hit by injuries and will be without big man LaMarcus Aldridge when the season resumes. Aldridge had season-ending shoulder surgery in April.
