The Cowboys traded veteran tight end Dante Rosario to the Chicago Bears for a conditional seventh round pick, per a source.
They now have an open roster spot less than a week before Sunday's season opener against the Giants.
Tight end was position of strength for the Cowboys as they had kept five tight ends on original 53-man roster on Saturday with Jason Witten, James Hanna, Gavin Escobar and Andre Smith joining Rosario.
The trade with the Bears was the third trade by Cowboys owner Jerry Jones in as many days. The Cowboys acquired defensive end Edgar Jones from the Chiefs on Saturday and traded defensive tackle Sean Lissemore to the Chargers on Sunday.
Postions the Cowboys could target for the extra roster spot include cornerback, defensive line and offensive line.
