The Boston Celtics and coach Joe Mazzulla have agreed to a multi-year contract extension, the team announced on Friday. Mazzulla enters his fourth year on the job as he looks for a second NBA title after leading the Celtics to their 18th franchise championship in 2024.

Joe Mazzulla has led the Celtics to the most wins in the regular season the past three years and secured a ring for the franchise in 2023-24.

Celtics president Brad Stevens has said throughout the offseason that the team wanted Joe Mazzulla to be its coach for a long time. It made that more than a proclamation Friday, announcing it has signed Mazzulla to a multiyear contract extension.
