McDonald played in the NHL for 12 years, playing for the Anaheim Ducks and St. Louis Blues. He was also a member of the 2007 Stanley Cup champion Ducks team. Over his career, he played in 685 regular season games, scoring 182 goals and 387 assists, for 489 points. Standing at 5'10" and weighing in at 175 pounds, McDonald was not a big player by any means, but he made up for his lack of size with his great skating ability.
This must have been an extremely difficult decision for McDonald, as he could have still played for another few years. However, this is what's best for him in the long run, as he's had five concussions to date. While no one was expecting this decision, it was certainly the right one.
