>>10498701She already did a spacewalk in an L suit. After doing that, she said the suit doesn't fit. Now for the next walk, that was supposed to be the all-female walk, there is an M and an L suit prepared. So the male astronaut is going to take her place. That male astronaut is also the only one that didn't do a spacewalk yet so maybe the female astronaut is also just saying it doesn't fit so he gets to do one, too.
