The Seahawks have added another option in their ongoing remodeling at tight end.
Seattle signed undrafted rookie Clayton Wilson on Monday. The free agent from Division-II Northwest Missouri State made good on his tryout chance in the Seahawks' rookie minicamp early this month.
Wilson is the fifth tight end on the 90-man offseason roster. The Seahawks didn't have to release anyone to make roster room for Wilson; they had an open spot after waiving backup quarterback Stephen Morris last week. Houston claimed Morris off waivers Monday.
The Seahawks let Jimmy Graham and Luke Willson leave in free agency in March, to Green Bay and Detroit, respectively.
