May suffered a broken fifth left metatarsal against Iona on Friday night.
"Everything went well and as expected," Taft said of the 75-minute surgery.
Taft put in a stainless steel screw and injected bone marrow from May's hip into the fracture site to enhance the healing process.
May is expected to be sidelined 8-10 weeks.
