Thomas (face) returned in the third quarter of Sunday's game against the Spurs, per the broadcast.
Thomas went to the locker room late in the first half after sustaining a facial cut, with Jalen Wilson starting the second half in his place. However, the guard returned to action at the 8:32 mark of the third quarter, though with the Nets facing a large deficit, the team may opt to rest him down the stretch in the fourth quarter.
