Megna has undergone surgery to repair a displaced fracture in his foot and will be sidelined for 4-6 weeks, Curtis Pashelka of The San Jose Mercury News reports.
Megna's extended absence will test the Sharks' depth at defense, but it shouldn't impact any fantasy lineups, as he's only picked up one goal through 19 contests this campaign. Another update on Megna should surface once he's ready to rejoin the lineup.
