Alternatively (and this can work without O2O if your local area doesn't allow them):

H/L: sees low block, throws flag

H/L: reports foul to R and U.
R/U: That TE was in the blocking zone, so we need to pick up the flag
H/L: picks up flag.

Seems to have worked pretty well when a wing or deep official observes an eligible receiver in the proximity of an incomplete legal forward pass deemed to have been intentionally in-completed. Simply adds relevant information to the penalty decision.
