Original sentence: The injury, had it been any more severe, would have resulted in Cernan being medically dropped from the flight and John Young commanding the last two moon landings of Apollo (as a note, fellow Group 2 astronaut Pete Conrad may have also done the same if he would have commanded the canceled Apollo 20 mission he was lobbying to be assigned to, but as he already flew as commander of Apollo 12, he was transferred to Skylab and Apollo 14 CMP Stuart Roosa would have likely flown on Apollo 20 as commander)
