The former England striker made his Reds debut as a 79th-minute substitute in Friday’s 1-1 draw at Barnet and Richardson will have to determine whether the player-coach has the necessary match fitness to start.
The 34-year-old has not started a league game since May 5, but will be a tempting option as the visitors seek to end a run which has seen them win just one of their last eight league games.
Richardson will be without loanee Rob Atkinson, who is ineligible for the trip to face his parent club.
The defender has been an ever-present since making the switch to the Crown Ground but his absence will give an opportunity to either Michael Liddle or Aristote Nsiala.
The Accrington manager has no other injury or suspension concerns.
St Johnstone manager Tommy Wright has urged his side to kick on from Saturday's fiery Tayside derby win over Dundee in the Ladbrokes Premiership.
