McKeon (anke) was activated from IR on Wednesday, Rob Phillips of the Cowboys' official site reports.
McKeon was injured in a preseason game against the Cardinals and was placed on IR on Sept. 3. The second-year pro played 14 games last season with the Cowboys -- primarily on special teams -- and never made a reception. His return comes at an opportune time since backup tight end Blake Jarwin (hip) is questionable for the Cowboys' Week 9 contest against the Broncos.
