Yesterday the Vikings added a bit of offensive line depth to their 90-man camp roster by signing center J.P. Quinn and waiving tight end Josiah Price.
Now we know why.
The team announced on Wednesday morning that Pat Elflein will begin Training Camp on the PUP (Physically Unable to Perform) list. Elflein is still recovering from the fractured ankle he suffered in the NFC Championship Game against the Philadelphia Eagles. Elflein will be required to be cleared by team doctors before returning to camp.
