Chelsea captain John Terry's substitution against Sunderland is being investigated.

The Mirror says his pre-planned Chelsea substitution in his final Stamford Bridge appearance is being investigated by the FA.

There is no suggestion Terry or anyone at Chelsea was involved in betting on the substitute market, but the Mirror claims the much-maligned PR stunt is being scrutinised.

Independent sport integrity commentator Chris Eaton says bookmakers should have been warned ahead of the orchestrated move.

He said: “If the manipulation of play to create the substitution and honouring opportunity was officially sanctioned, no problem except that the sport bookmakers should have been warned and could have avoided losses.

“There should be no unsanctioned manipulation of the free flow of competition permitted by the rules of the game.

“Play and competition without fail should be honest, clean and earnest."
