Rivero (hand) was returned from his rehab assignment Monday.
Rivero appeared in five minor-league games as part of his rehab assignment, going 1-for-14 in that span. It's unclear whether he's suffered a setback or is ready to return to action. If he's cleared to be taken off the IL, then Rivero would likely be optioned to Triple-A Salt Lake, given that the Angels carry three catchers on the 26-man roster in Tyler Heineman, Travis d'Arnaud and Moises Ballesteros.
