Source: BBC SportLiverpool manager Brendan Rodgers said he would review television footage of an incident where Luis Suarez appeared to bite Chelsea's Branislav Ivanovic.
The Reds striker clashed with the Serbian defender during the second-half of the 2-2 draw at Anfield.
"I can't say anything on it until I review the incident," Rodgers told BBC Sport in his post-match interview.
Chelsea interim boss Rafael Benitez also refused to comment on the incident.
Former Ajax captain Suarez accepted a seven-match ban for biting PSV Eindhoven midfielder Otman Bakkal in November 2010.
Ex-Liverpool defender Mark Lawrenson, who was covering the match for BBC Radio 5 live, said referee Kevin Friend would have sent off the Uruguayan had he seen the incident.
