"Tentative return to play is six to eight weeks," the Phillies reiterated.
That means Revere could be back anywhere between late August and mid-September.
Revere fouled a pitch off the ankle in the 11th inning of Game 1 of Saturday's doubleheader against the White Sox.
"It's one of those deals," Revere said Sunday. "It's part of the game. I've probably hit a couple balls on the same spot a couple times and really nothing happened, except a bruise. But it was good the next day. But this was finally the one that cracked it."
General manager Ruben Amaro Jr. said Sunday the Phillies will be looking to acquire a center fielder before the July 31 Trade Deadline to replace Revere while he is out.
