Original post, 10 a.m Tuesday: In the end, quarterback Kellen Moore's separation from the Cowboys wasn't that long.

A source told SportsDay's David Moore Tuesday that the Cowboys and Moore have agreed in principle to a new deal expected to be signed in the coming hours. The agreement comes after Moore was cut as part of the Cowboys' roster trim down to 53 on Saturday.

Moore, who had taken most of the second-team snaps throughout training camp, appeared in some eyes to have been surpassed for the No. 2 job by undrafted rookie Cooper Rush, who was part of the 53-man roster.

Earlier Tuesday morning, Cowboys owner Jerry Jones told 105.3 The Fan in his weekly radio address that the team would re-sign Moore. The expected IR listing of tight end Rico Gathers (concussion) makes room for another roster spot once that move goes through.
