The Seahawks continued to add help at tackle Monday following George Fant's season-ending knee injury, acquiring tackle Matt Tobin and Philadelphia's 2018 seventh-round selection in a trade with the Eagles. The Eagles will receive Seattle's 2018 fifth-round selection.
Tobin, 27, has played both guard and tackle for the Eagles, and started 13 games in 2015. Tobin, who began his career as an undrafted free agent out of Iowa, has appeared in 42 games over the past four seasons, starting 21.
Tobin is the second offensive line addition for Seattle after the signing of free agent Tyrus Thompson.
Tight end Marcus Lucas was waived/injured to make room on the 90-man roster. Lucas, who sustained an ankle injury in Friday's preseason game, will be placed on injured reserve if he clears waivers.
