Phoenix Suns forward Kelly Oubre Jr. underwent a minor procedure on his left thumb and will miss the rest of the season, the team announced Friday.

Oubre is expected to make a full recovery in four to six weeks.

Oubre, 23, will enter into restricted free agency this summer off the best stretch of his career, as he has averaged 20 points and 5.7 rebounds since his insertion into the starting lineup after the All-Star break. Oubre joined the Suns in December in a trade from the Washington Wizards.

Oubre is averaging a career-best 15.2 points a game this season. He is expected to be a priority for the Suns to retain in free agency this summer. They'll have the right to match an offer sheet elsewhere for him.
