Celtics bring back Gerald Green, re-sign Tyler Zeller

The Celtics have agreed to a one-year contract with free agent forward Gerald Green. The deal is for the veteran’s minimum of about $1.5 million.

Also, the Celtics have re-signed center Tyler Zeller to a two-year, $16 million contract. The second year of that deal is non-guaranteed giving the Celtics added roster flexibility.

The Celtics are nearing an agreement on a guaranteed contract with point guard Demetrius Jackson, the 45th overall pick of last month’s draft, and are close to signing former Providence forward Ben Bentil, the 51st overall pick of the draft, to a partially guaranteed deal.
