With tight end Irv Smith Jr. on the mend following thumb surgery, the Vikings are pressing forward with their unproven crop of tight ends.
Johnny Mundt, Ben Ellefson and Zach Davidson rotated with the first-team offense on Wednesday, with Mundt — the ex-Rams backup who signed a two-year deal in free agency — getting the most run with the starters. Coach Kevin O'Connell said he wants to evaluate their depth in camp before looking for external options. The Vikings' current crop of tight ends have a combined 11 career catches for 103 yards in the NFL.
