The FA have confirmed they have asked betting companies to provide them with any relevant information relating to John Terry's substitution on Sunday.
Terry was withdrawn and given a guard of honour in the 26th minute of Chelsea's final Premier League game of the season as part of the club's tributes to their long-serving defender, who will leave the club this summer.
Sunderland, Chelsea's opponents on the day, were aware of the orchestrated plan, which Terry has said was his idea, and the Premier League is understood to be relaxed about the matter, which did not contravene its rules.
Bookmaker Paddy Power accepted the bets on Terry being substituted between 26:00 and 26:59 in Sunday's match, at odds of 100-1.
At this stage, there is no evidence of any suspicious betting patterns in the market but independent sport integrity commentator Chris Eaton says bookmakers should have been warned ahead of the orchestrated move.
"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," Eaton, a former head of security at FIFA and former head of operations at INTERPOL, said.
"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."
