Broncos acquire John Moffitt, trade Sealver Siliga to Seahawks Posted by Michael David Smith on August 20, 2013, 6:23 PM EDT AP For the second day in a row, the Seahawks have traded guard John Moffitt. On Monday, the Seahawks shipped Moffitt to Cleveland in a trade for defensive lineman Brian Sanford. But that trade was voided because the Browns had some concerns about Moffitt’s health. Shortly after that trade to Cleveland was voided, the Broncos announced that they have acquired Moffitt. Denver shipped defensive tackle Sealver Siliga to Seattle to acquire Moffitt. It is not clear whether the Broncos are aware of Moffitt’s health issue and are not as concerned about it as the Browns were, or if it’s still possible that Moffitt could fail the Broncos’ physical, and that this trade could be voided, too. A 2011 third-round draft pick, Moffitt started nine games as a rookie and six games last year. Siliga entered the NFL as an undrafted free agent in 2011 and has played in just one regular-season game.
