Dolphins release Pat Devlin to sign Brady Quinn

Earlier today, the Miami Dolphins agreed to terms with quarterback Brady Quinn, adding a veteran to the depth chart as the club deals with injuries to other passers.  Tonight, word of the corresponding roster move broke, with the team releasing one of their backup quarterbacks to make space for Quinn.

In a little bit of a surprise, the backup quarterback released was fourth-year, third-string signal caller Pat Devlin, according to the Miami Herald's Armando Salguero.

Devlin joined the team in 2011 as an undrafted free agent.  He worked his way up from the practice squad to being a member of the 53-man roster, and a player considered to be a favorite of the coaching staff.  The team had hoped he would eventually succeed Matt Moore as the second string player behind starter Ryan Tannehill, but his development seemed to stall this year.  He's failed to ever mount any sort of competition with Moore.

After starting his college career at Penn State, Devlin moved to Delaware for his final two seasons as a collegiate.  He has no NFL regular season appearances.  He has missed the last few practices, and the team's first preseason game over the weekend, with a hamstring injury.
