With three centers sidelined, the Oklahoma City Thunder are adding to their frontcourt by signing 7-footer Branden Carlson, the team announced Saturday.

Carlson comes from the Toronto Raptors 905 of the G League, where he played after a standout collegiate career at Utah. He averaged 14.3 points, 8.7 rebounds and 3.0 assists per game to start the G League season.

The Thunder, who had one open roster spot, scanned the market in recent days after losing big man Chet Holmgren for at least two months due to a right iliac wing fracture in his hip area that he suffered on Sunday. Centers Isaiah Hartenstein (hand) and Jaylin Williams (hamstring) also remain sidelined.

Since Holmgren’s injury, the tallest players in the Thunder’s starting lineup last week were 6-6 Jalen Williams and Shai Gilgeous-Alexander.

Oklahoma City won its third straight game on Friday night, defeating the Phoenix Suns 99-83 to improve to 11-2.
