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

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

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.
