The Thunder have formally signed first-round pick Andre Roberson to a rookie-scale contract, according to RealGM.com's transactions log.
Roberson, 21, was selected 26th overall by Oklahoma City last month, after the club moved up three spots to snag him. The 6'7" forward averaged a double-double in his junior year at Colorado, recording 10.9 PPG to go along with 11.2 RPG.
Roberson will likely receive a first-year salary of about $1.11MM, 120% of his rookie-scale cap hold.
