For the short term, at least, Trammell has said Uggy will keep closing games and Percy will work himself back in non-save situations.
Beyond that, there has been no committment from anyone, so everything here is speculation.
My own 2 cents is that it will be hard to yank Urbina out of that role unless he has a couple of rocky outings (and at the same time Percival pitches lights-out). Trades and injury relapses blow up everything, and none of us can make that call now.
For fantasy, I'd hang onto both and keep the fingers crossed.
