O'Connell joined the Dolphins back in August, looking to serve as a backup to either Chad Henne or Matt Moore. Henne eventually secured the starting role, Moore the second string position, and rookie Pat Devlin was thought to have the inside track to the third slot. That left O'Connell without a roster position.
That's now been confirmed.
O'Connell was selected by the New England Patriots in the third round of the 2008 NFL Draft. He actually made his regular season debut against the Dolphins in the fourth quarter of the September 21, 2008 match-up between the two division rivals. The Patriots waived O'Connell three days after starting quarterback Tom Brady was injured in the 2009 preseason.
WIth the Jets, O'Connell served as a backup quarterback, before being place on injured reserve, missing the entire 2010 season.
O'Connell threw one pass with Miami this preseason, and ran four times for seven yards.
