Derry Matthews jumped ship to Warren?

Judging by Dave coldwell's twitter and the subsequent responses, Derry may have jumped to Queensbury.

Bit surprised if this is the case, just because Derry was getting Sky dates and Coldwell and him seemed matey. Must have been thrown some wonga to join Warren. Makes little sense to me since he could have made good money against Mitchell and that won't happen now.

Here is his tweet:

'Gutted I found out on twitter, thought I was worth a call, a pick up frm mine or even a text.
But its been a successful ride & thats boxing.'
