Northamptonshire chief executive David Smith has apologised for criticising the Old Trafford pitch.
Smith was furious after Northamptonshire lost to Lancashire inside just two days in an LV= County Championship clash last month - and pointed the finger at the state of the Old Trafford surface.
He said at the time: "Was this a good wicket? Was it a fair contest between bat and ball? No.
"This should have been a showcase Division Two game between the top two teams, and it was not allowed to be."
The pitch was subsequently adjudged to be satisfactory by pitch inspector Jack Birkenshaw and the ECB "formally reprimanded" Northamptonshire and "reminded them of their responsibilities."
