Cornerback Lorenzo Doss signed his first NFL contract Thursday, joining nose tackle Darius Kilgo and center/guard Max Garcia as 2015 Broncos draft picks to sign their deals.

Doss, a fifth-round pick from Tulane, hopes to replicate the ball-hawking success he had with the Green Wave, for which he intercepted 15 passes over the last three years.

The 21-year-old cornerback made his on-field debut at last weekend's rookie camp.

With Doss signed, the Broncos now have six draft picks left to go. Last year, the team signed all of its draft picks by June 10.
