covered tight end

[johnyd]

Wide out identified and confirmed as on the line.
Tight end made a late switch and also lined up on the line, now covered by the wide out and "Covered" so ineligible.
At Snap QB drop backs, and both tight end and wide out go down field for a pass.
QB then tucks ball and runs.
When do you throw the flag?
Confirm call is ineligible receiver downfield?
COnfirm, throw flag and let play continue because defense has the chance to intercept.
Anything else I am missing?
