She will be taking on Maricela Cornejo who is a late replacement after Hanna Gabriels was forced to pull out due to a failed drugs test. 

Cornejo comes into this fight on the back of a first round knockout win over Sheila Cunha in March, but this encounter will be a huge step up.

Shields will be a clear favourite and if she emerges victorious, there are a number of huge fights to be made including a rematch with Savannah Marshall.
