The Moose is back in the NBA. According to Shams Charania of The Athletic and Stadium, the Boston Celtics have signed free-agent center Greg Monroe to a 10-day contract.

The move comes as the Celtics deal with a rash of minor injuries to key performers with the playoffs fast approaching. Al Horford, Gordon Hayward and Aron Baynes are all unavailable for Boston's game against the Charlotte Hornets on Saturday while recovering from Wednesday's hard-fought loss to the Philadelphia 76ers.

With Horford resting his fragile right knee and Baynes nursing an ankle sprain, Brad Stevens would have been left with backups Daniel Theis and Guerschon Yabusele as the only true big men available to play versus the Hornets if the Celtics hadn't signed Monroe.

A nine-year veteran, Greg Monroe signed a single-season deal with the Toronto Raptors last August. He was traded with a 2021 second-round pick to the Brooklyn Nets in exchange for cash, a deal that saved Toronto nearly $2 million in luxury tax payments.

Monroe was immediately waived by Brooklyn upon completion of the trade. He averaged 4.8 points and 4.1 rebounds in 11.1 minutes per game over 38 appearances with Toronto, two of which were spot starts.

This is the second consecutive season Boston has signed Monroe toward the end of the regular season. He played 26 games with the Celtics in 2017-18, at times emerging as a major factor off the bench. He averaged 10.2 points and 6.3 rebounds during that period.
