United and Liverpool are due to meet at Anfield on Sunday. So far, there has been no request for the pre-match handshake to be cancelled.
Speaking on Match of the Day 2 on Sunday, Dion Dublin said football authorities should "do away" with enforced handshakes and said Ferdinand and Terry had been "forced" to shake hands against their will.
"I think it is wrong," said the former England and Manchester United striker. "If you have play against an opponent, after the game shake their hand. Leave them to deal with the situation themselves."
Terry was accused of racially abusing fellow defender Ferdinand during a Premier League match last October. The Chelsea man was cleared in court but faces an FA charge later this month.
Handshakes were abandoned in the return league game between the west London clubs last season, as well as before their FA Cup tie.
