The Miami Dolphins signed quarterback Brady Quinn today, according to a report from NFL Network's Jeff Darlington. The team held tryouts for Quinn, along with John Skelton and Rex Grossman, earlier in the day.
Quinn joins a roster with starter Ryan Tannehill entrenched atop the depth chart, followed by two injured quarterbacks in Matt Moore and Pat Devlin. Moore returned to practice this week, but the team is still worried about his health.
The Dolphins also have Seth Lobato under contract, though releasing him to make room for Quinn on the 90-man preseason roster would be the most likely scenario. [Editor's update: The Dolphins have released Devlin to make the roster space for Quinn, according to a report.]
The former Notre Dame quarterback initially joined the NFL as a first round selection of the Cleveland Browns of the 2007 NFL Draft. After three years with the Browns, he was traded to the Denver Broncos, where he spent two seasons. In 2012, Quinn joined the Kansas City Chiefs as a free agent. Last season, Quinn spent brief periods with the Seattle Seahawks and New York Jets before serving as the backup to Kellen Clemens with the St. Louis Rams for most of the year.
Quinn has a career record of 4-16, with a 53.8 completion percentage. He has 3,043 career passing yards, with 12 touchdowns and 17 interceptions.
The Dolphins were in need of a quarterback for the back end of the depth chart, especially with the injuries to Moore and Devlin. Lobato, who played most of Friday night's preseason game against the Atlanta Falcons, was not impressive, and the team was hoping he would at least challenge Devlin for the third quarterback position. The club could also be looking for someone to challenge Moore for the top backup position behind Tannehill.
