Muscala (ankle) didn't practice Tuesday, Joe Mussatto of The Oklahoman reports.
Muscala was a late scratch for Monday's 102-89 loss to the Rockets, and he may be in danger of missing a second straight game Wednesday. Derrick Favors (non-COVID illness) also didn't practice Tuesday, so Isaiah Roby could once again operate as the primary backup to Jeremiah Robinson-Earl against Houston.
