Dallas signed Callaway to a reserve/future contract Wednesday, Todd Archer of ESPN.com reports.
Callaway reached an injury settlement with the Chiefs at the end of August, and after moving past a knee issue, he latched on with the Cowboys' practice squad in mid-November. He was never elevated during the regular season and hasn't seen NFL action since 2020, but with his new contract, he'll be able to stick around in Dallas' organization and compete for a roster spot during the offseason.
