That interest appears to be genuine, as Adam Caplan of TheSidelineView.com reports that Carlson will visit Minnesota headquarters on Wednesday.
The Vikings are in danger of losing free agent tight end Visanthe Shiancoe. While 2011 second-round pick Kyle Rudolph is ready for a full-time role, Carlson could slide in as the Vikings’ No. 2 tight end.
Carlson missed all of last season with a shoulder injury, but he was highly regarded coming out of Notre Dame in 2008. The Seahawks made him the 38th overall pick in that draft.
