Well, The crew that was supposed to go on Apollo 13 was Alan Sheppard's crew, but he got an ongoing ear infection so he and his crew got bumped. Afterwards, Jim Lovell and his crew (Fred Haise, and Ken Mattingly) were assigned for the Apollo 13 mission, but because the doctors thought Ken Mattingly was going to have the measles, he got bumped from the mission and was replaced with Jack Swigert. Hope this helps! :)
Alan Shepard and his crew was supposed to fly Apollo 13, but he got an ear infection close to the launch, so the crew of Apollo 14 were moved up a place allowing Alan Shepard to fly Apollo 14. The reason the whole crew switched was because they trained with each other and were put together to compliment each others skills.
Apollo 13
Jim Lovell and Fred Haise were the original crew, but jack Swigert joined in as Ken Mattingly fell ill.
John Swigert was at the commanding seat when the Apollo 13 crew got the call to stir the oxygen tanks.
