Dorsey's hopes of becoming a starter for the Cleveland Browns became much more bleak after the Browns drafted quarterback Brady Quinn of the University of Notre Dame with the 22nd overall pick in the 2007 NFL Draft. Charlie Frye, Derek Anderson, Quinn, and Dorsey battled for position on the Browns' QB depth chart throughout the 2007 NFL Pre-season. On September 1, 2007, the Browns released Dorsey. After a disappointing loss to Pittsburgh in Week 1, Frye was traded to Seattle and Dorsey was re-signed by the Browns in a reserve role. Derek Anderson had a break-through season in 2007, further diminishing the chances of Dorsey receiving playing time.
