This move comes as no surprise.  The Dolphins had traded Wilkinson to the Denver Broncos but he failed to report which nixed the trade.  So the Dolphins decided to cut their losses so they released him anyways.  Wilkinson played in 10 games for the Dolphins last season and he only made 13 tackles, defensed 3 passes and forced 1 fumble.  This is likely the end of the 34-year olds NFL career.
