If they are both getting done, then they would have the same needs for the cage (no levels or things to jump on, no shavings etc). If the cage is large enough, they should be fine together. You may want to give 2 food bowls so you can try to monitor eating habits better.
If you do find there is an issue with one not eating or something, you may need to separate them. You should keep the cages close so they can still see and smell each other. Once they get healed enough for some running around, you can let them out together. If there are no issues, then this should not be needed.
Just keep a close eye on both of them, especially during the first couple days to make sure they are eating. With 1, you can see that the food is being eaten, but with 2 together it can be harder if one is eating it all.
Hopefully they will be fine and not have any issues.
