Just monitor him. Make sure he is still eating, drinking and pooping. If anything changes or he stops take him to the vet A.S.A.P
How big is he?
I would remove him from the current substrate you have and change him to something else, I would also start feeding outside the cage in another bare container to prevent this from happening again.
Again... just watch for signs of impaction. Depending on the size of the piece he ate and his size there may or may not be a problem.
