Vikings free-agent TE Visanthe Shiancoe will visit the Seahawks within the next few days, according to a source with knowledge of the situation. The Seahawks will take a look at Shiancoe to fill the void left by John Carlson, who incidentally signed with the Vikings on Wednesday. The Vikings will pair Carlson with Kyle Rudolph, the team’s second-round pick last season. The Seahawks currently have Zach Miller, Anthony McCoy, Cameron Morrah and John Nalbone on the roster.
