Source: Orton signs first-round tender

4/16/2010 - NFL Kyle Orton Denver Broncos + more

Denver quarterback Kyle Orton signed his restricted free-agent tender, according to a league source.

Orton was given a first-round tender. By signing his tender, Orton is now under contract, and it removes all concern that the quarterback could hold out from minicamps and training camp.

Orton signed an injury waiver to participate in the Broncos' offseason workout program, indicating there would not be any issues between him and the team. Orton said he needed to take part in the workouts because of his leadership position.

Orton is entering his second season in Denver. Coach Josh McDaniels has said Orton deserves to remain the starter despite Denver acquiring Brady Quinn this offseason. Last season, Orton threw for 3,802 yards and 21 touchdowns with 12 interceptions.

McDaniels added that Orton will have to keep his starting job through performance and continued improvement or Quinn could supplant him.

Denver defensive end Elvis Dumervil has yet to sign his tender. The restricted free-agent signing period ended Thursday night.
