CLEVELAND — Brandon Weeden will have to fight off a proven veteran to keep his starting job with the Browns.

Cleveland signed free agent quarterback Jason Campbell to a two-year contract Tuesday night, bringing him in to provide competition for Weeden, who had an uneven rookie season in 2012.

Campbell has started 71 career games for Washington, Oakland and Chicago since being drafted by the Redskins in the first round (25th overall) in 2005. The 32-year-old will provide a legitimate challenge to Weeden, and his arrival could mean the Browns will part ways with former starter Colt McCoy.
