The BBC article says both are leaving. They talk about Dan, but no more information about the Mark Irish situation.
LM says: 'Dan's a good Championship player and he'll do doubt play against us in the future but I felt it was the right decision in terms of progressing to where we want to be.
I think that makes sense, as long as we have a better 8 to replace him - at the moment we no longer have a specialist 8 at all.
Mark Irish is too good to release like this, so I can only imagine we'll see him in the Prem next season...
