The Boston Celtics have signed forward Jayson Tatum to a five-year, $195 million extension, according to ESPN’s Adrian Wojnarowski via Tim Bontemps. The deal includes a player option for the fourth year.

“The full designated rookie max of $163 million could go up to nearly $200 million with All-NBA escalators, sources said.”

Tatum, who was selected third overall in the 2017 NBA Draft, made his first All-Star team last season and helped the Celtics to the Eastern Conference Finals. He averaged career highs of 23.4 points, 7.0 rebounds and 3.0 assists per game.

The 22-year-old scored 39 points in a notable win over the Los Angeles Clippers prior to the All-Star break and notched 41 in a loss to the Los Angeles Lakers shortly after.

This latest development leaves Boston with both Tatum and teammate Jaylen Brown locked up through to the 2023/24 season and one of the best young foundations in the league.
