I can't speak to Allen's issue, other than to say that his claim of being unaware that he'd been DQ'd is completely plausible given my personal experience with med staff, and it is congruent with what has been related to me by others in their dealings with Tucker.
I CAN, however, state, yet again, that 5 of 7 specialists cleared Steven during their initial consultations; DiFino reversed his decision after speaking with Kouides. A grand total of 6 specialists for, a GP against. Parenthetically, Allen does NOT have Factor 5 Leiden (stated in Bailey's article). Goes to show you that tragedies can occur, without warning, on or off the field. Each one of those specialists stressed to us that the risk to Steven is minimal; only slightly more than you sitting on your couch.
