McCarron, who was selected with the 25th pick, recently participated in the team's development camp. He had been committed to attend Western Michigan University in the fall but now will spend the 2013-14 season with the London Knights of the Ontario Hockey League.
McCarron spent the past two seasons playing for the United States National Team Development Program. The 6-foot-5, 228-pound right wing had 29 points and 166 penalty minutes in 49 games last season with the USNTDP under-18 team. He also played a key role internationally for the United States, posting three goals and five points in helping the U.S. team win the silver medal at the 2013 IIHF World Under-18 Championship.
