Dez Bryant and Demaryius Thomas will likely receive franchise tags this offseason in free agency.

The Dallas Cowboys and Denver Broncos have been unable to make progress on extensions with their star wide receivers.

Bryant's negotiations have grown somewhat contentious, sources said. The Cowboys thought a deal with Bryant was close before the season started. Bryant has since changed agents, which displeased Jerry Jones.

Top receiver deals can average over $15 million per season, and with the franchise tag set at just under $13 million. Players could be franchised twice in a row if need be, at roughly $30 million total.

The Cowboys have to contend with DeMarco Murray's free agency, while the Broncos need to keep Julius Thomas.
