Oklahoma City ensures its young All-Star forward will stay put with a deal reportedly worth up to $287 million.

The Oklahoma City Thunder have crossed their I's and dotted their T's. They have signed Jalen Williams to a five-year, $287 million contract extension that'll keep him in OKC through the 2030-31 season. There are some incentives involved, but it's the most money the 24-year-old could've gotten.

The recently crowned NBA champions have agreed to a five-year maximum rookie contract extension, ESPN's Shams Charania reported Thursday.
