Robert Williams III has agreed to a contract extension with the Portland Trail Blazers that will keep him with the team through the 2028-29 season, a person with knowledge of the deal told The Associated Press. 

The person confirmed the deal on the condition of anonymity because it had not yet been announced publicly. The extension was first reported by ESPN on Tuesday. 

Williams, 28, averaged 6.7 points, 7.0 rebounds and 1.5 blocks a game this season, becoming a key contributor off the bench for Portland, which made the playoffs for the first time in five seasons. 

The six-foot-10 center averaged 17.1 minutes a game in 59 games, but he did not play in back-to-back games for the Blazers after struggling with knee injuries for the previous two seasons.

It was the second move the Blazers made in as many days. On Monday, the team traded forwards Jerami Grant and Kris Murray to the Memphis Grizzlies in exchange for Ja Morant.
