The Indianapolis Colts have added long snapper Matt Overton to the roster.  Overton was originally signed by the Seahawks in 2007 as a rookie free agent but was released.  He signed with the Seahawks again in 2010 and recently spent time in the UFL.  Colts snapper Justin Snow has been with the team since 2000 and been unchallenged since winning the job in his rookie season.
