A day before the deadline to solidify their final roster, the Broncos traded offensive tackle Ty Sambrailo, a former second-round pick, to Atlanta for a 2018 fifth-round draft selection.

The Broncos gain a future draft pick in exchange for a tackle that wasn’t going to make their 53-man roster, according to a source.

Sambrailo, a former Colorado State standout, bounced in and out of the starting lineup since his rookie year in 2015, in part because of injuries but also because of performance. His first season was cut short to three games because of a shoulder injury that landed him on injured reserve. Last season, he played 10 games, starting four, and yielded seven sacks.

Sambrailo’s status was in jeopardy when tackle Donald Stephenson agreed to restructure his contract to eliminate his 2018 salary and reduce his cap hit for 2017. But Sambrailo’s future was in question long before when first-year head coach Vance Joseph and offensive coordinator Mike McCoy changed the blocking scheme, requiring linemen to play both power and zone, and often multiple positions.

The Broncos’ remade offensive line got bigger and stronger and, though Sambrailo packed on pounds during the offseason, he didn’t appear to be the right match.

Thursday night, in the preseason finale against Arizona, the Broncos tested Sambrailo at center to see if he could serve as both a tackle and center, a key for Joseph as he mulled his options for reserve linemen.

“Our backup four or five linemen, we want those guys to have flexibility in positions,” Joseph said earlier in the week.

Sambrailo’s exit leaves the Broncos with an offensive line that features already appointed starters in left tackle Garett Bolles, center Matt Paradis and right guard Ron Leary. It’s likely the Broncos will keep both Max Garcia and veteran Allen Barbre to play guard, as Joseph hinted earlier in the week, and it’s likely Menelik Watson and Stephenson will share duties at right tackle.
