How can I fix my football (surface) which has been creased badly?

For packing purposes the football (adidas top training) was deflated.
Then I pumped air in and one side is badly ruined in that it is creased.
Is there a way to flatten/smooth out the surface???
I heard something about most football being made from pig skin leather.
Can I adopt one of the ways of unwrinkling (just normal) leather?
PLEASE HELP!!! THANKS.
