The AFL will award retrospective Brownlow medals to Sam Mitchell and Trent Cotchin for the 2012 AFL season.

Original winner Jobe Watson, after consultation with the league, will hand back his medal, won at the height of the Essendon supplements regime.

AFL Chairman Mike Fitzpatrick (pictured) says it was a difficult decision to make but the only one that could be under the Brownlows eligibility rules.
