Zepp suffered a right leg injury Saturday while playing for AHL Lehigh Valley, Sam Carchidi of the Philadelphia Inquirer reports. Though the NHL club is in need of an extra goalie after Steve Mason suffered a lower-body injury Sunday, Zepp's own ailment will take him out of the running for a promotion. Instead, it looks like 21-year-old Anthony Stolarz will get the call to Philadelphia, where he'll serve as the backup to Ray Emery for the duration of Mason's absence.
