Need help with Madden 16 MUT contracts
 

My 11 year old is playing MUT on 360 and let the contracts lapse for a few of his elite players. Since they have no contracts they're out of the line-up.

When I try to swap them in, I get an error message that says you can't use a player with no contracts in your line-up. Add contracts and try again.

The only time I see an opportunity to add contracts is when a player is already in the line-up. Am I missing something obvious?

Thanks
