Thomas will start in Saturday's game against the Knicks, Serena Winters of FanDuel Sports Network Ohio reports.
With Cleveland missing Jaylon Tyson (ankle), Jarrett Allen (knee) and now Sam Merrill (right elbow management), Thomas will earn the second start of his young NBA career. He posted 17 points (7-16 FG, 3-9 3Pt), five rebounds, one assist and one steal across 26 minutes in his first career start against the Thunder on Nov. 2.
