The Boston Celtics have reportedly signed free-agent center Luka Garza to a two-year contract worth $5.5 million.

The addition of Garza will soften the blow of losing Kornet, but Boston will need to do some work -- potentially a lot -- to shore up their big men.

Garza's two-year deal comes after the Celtics lost Luke Kornet to the Spurs, and could potentially lose Al Horford as well.
