The Flyers signed two prospects - forwards Derek Mathers and Andrew Johnston - to entry-level deals on Monday.
Mathers, 18, was the Flyers' last draft pick in 2011, 206th overall in the sixth round. He collected an astounding 348 penalty minutes over the last two seasons, including 49 fighting majors, with Peterborough of the Ontario Hockey League. The 6-foot-3 bruiser added two more fights in nine games with the AHL's Phantoms this spring on an amateur tryout contract once his OHL season was finished.
