Peterson revealed Tuesday via his personal Instagram account that he underwent surgery to repair a fractured bone in his right foot, Anthony DiComo of MLB.com reports.
Assuming the procedure went as anticipated, Peterson will have a chance to make it back from the 60-day injured list at some point in September, but he likely won't have enough time to build back up for a starting role. Before suffering the toe injury, Peterson made 15 starts for the Mets, posting a 2-6 record, 5.54 ERA and 1.40 WHIP.
