RENTON, Wash. (AP) — Offensive lineman John Moffitt was traded Tuesday from the Seattle Seahawks to the Denver Broncos after his original trade to Cleveland was voided by the Browns.

The Broncos, who announced the trade, sent defensive tackle Sealver Siliga back to Seattle in exchange for Moffitt.

Seattle had originally traded Moffitt to the Browns on Monday, pending a physical, in exchange for Brian Sanford. But the trade was voided by the Browns. The Seahawks then turned and sent Moffitt to the Broncos, providing Denver with some experienced depth. Moffitt became expendable after he lost out to J.R. Sweezy for the starting right guard spot. Seattle also felt strongly about some of its other young backups.

"We would not have been able to do a trade like that if the young guys hadn't been doing such a great job," Seattle coach Pete Carroll said Tuesday before Moffitt's deal to Cleveland had been voided and the new trade completed. "I think that it's really a statement about those guys growing and coming in and helping us."

Seattle has been set on adding additional depth to the defensive line. Seattle signed Tony McDaniel in the offseason to play defensive tackle, but he has been slowed by a groin injury during training camp. The Seahawks also have Clinton McDonald and Jaye Howard, and they drafted Jordan Hill and Jesse Williams in April to play the position.

Siliga doesn't come with much experience. He played in just one game during the 2012 season for the Broncos and recorded one tackle. He left Utah after his junior season, but went undrafted. He originally signed with San Francisco before being released and latching on with Denver's practice squad in October 2011. Silaga was on Denver's 53-man roster for all of the 2012 season, but he was inactive for 15 games.
