Killer Croc VS Silver Sable and Black Widow

Seeing as how Killer Croc from the DC Universe does best if he's sent up against street level characters, I decided to give him a battle between two street level femme fatales from the Marvel Universe. The Silver Sable and the Natasha Romanov Black Widow! Now, there are three ways this will be done, and in each of the three fights, no prep for anyone and morals apply for everyone. Also, all three take place in the plains of Africa. Who would win if it was Killer Croc VS Silver Sable only? Who would win if it was Killer Croc VS Black Widow only? And finally, who would win if it was Killer Croc VS Silver Sable and Black Widow both at once? No jobbing for any of the fights, btw. I don't want any of that bullshit or WIS/CIS/PIS crap getting in the way of this battle!
