Blake Griffin has agreed a one-year, fully guaranteed deal with the Boston Celtics.

Griffin spent the past season and a half with the Brooklyn Nets.

Griffin will give Boston depth in the frontcourt following the injuries to Robert Williams III and Danilo Gallinari.

The Celtics now have 11 fully guaranteed contracts on their roster, though that number does not include Al Horford's mostly guaranteed deal.

Griffin averaged 6.4 points and 4.1 rebounds across 56 games (24 starts) this past season for the Nets.
