Stewart wasn't on the bench, Carlester, so it's possible that he'll remain out during this swing of the road trip, which concludes Sunday against Kentucky. Robert Morris returns home after that, so it's possible that Stewart may return against Texas-Arlington.
That's my guess, since RMU's plan is to stay on the road and not return to campus. But it's possible that he's with the team and simply wasn't allowed to be on the bench per the stipulation of his suspension.
Either way, I'd expect him back next Thursday at the latest and possibly before that.
