Premier League - Video: Did Suarez deserve a red card?
The incident occurred late on in Liverpool's 4-1 Premier League win at Anfield as the players chased a ball.
As Ivanovic attempted to shepherd the ball out for a goal kick, Suarez appeared to haul the Serbian down.
Referee Kevin Friend did not award a free-kick, and if it is established he did not see the incident, Suarez could face retrospective action.
Ivanovic could count himself lucky still to be on the pitch at that stage - earlier on he conceded his penalty by delivering a forearm to the midriff of Liverpool striker Andy Carroll.
Referee Friend settled for a yellow card, meaning Ivanovic cannot face any further action.
