McCray signed an Exhibit 10 contract with the Thunder on Friday, Clemente Almanza of USA Today reports.
McCray was previously on an Exhibit 10 deal with the Lakers, whom he joined for Summer League play. He's now with the Thunder and could compete for a spot on the team's regular-season roster. However, the guard out of Florida State may still be waived before training camp begins, as the Thunder own his G League rights.
