Manchester City defender Ben Thatcher has apologised to Pedro Mendes for the horror challenge which left the Portsmouth midfielder in hospital with head injuries.
The 30-year-old is being investigated by both the Football Association and Greater Manchester Police as a result of the forearm smash which pole axed the Portugal international during Wednesday's goalless draw at Eastlands.
Thatcher has now attempted to make amends by sending a letter of apology to Mendes, who was released from hospital on Thursday morning.
A statement on City's official website read: "Manchester City can confirm that Ben Thatcher has personally written a letter to Pedro Mendes to apologise to him following the tackle in the match last night.
"Chief executive Alistair Mackintosh has this morning telephoned Portsmouth's chief executive Peter Storrie to enquire about Pedro's health.
"The two clubs share an excellent relationship and everyone at Manchester City, especially Ben himself, wishes him the very best."
The statement continued: "The club does not condone such action and the matter has been dealt with internally by Stuart Pearce."
