Kyle Sinckler could be facing a lengthy ban after he was cited for biting in the British and Irish Lions' second Test defeat by South Africa on Saturday.

The incident is alleged to have taken place during a ruck in the 64th minute of the 27-9 loss at Cape Town Stadium.

"British and Irish Lions player Kyle Sinckler will attend an independent disciplinary hearing after he was cited by Scott Nowland (Australia) for an act of foul play contrary to Law 9.12 (biting) during the 64th minute of the second test against South Africa in Cape Town on 31 July, 2021," a statement from World Rugby said on Sunday.

England prop Sinckler, who has a chequered disciplinary record, will be hit with a minimum 12-week ban if the citing is upheld by Tuesday's disciplinary hearing.

The Lions earlier released a statement in which Stuart Hogg denied he had bitten the arm of Springbok fullback Willie le Roux after pictures emerged on social media.

Saturday's ill-tempered second test, which was won 27-9 by the Boks to level the three-game series heading into Saturday's decider in Cape Town, had a number of flashpoints.

South Africa wing Cheslin Kolbe was fortunate to escape a red card when he connected with airborne Lions scrumhalf Conor Murray. He was sent to the sin-bin.

Images on social media also showed Lions lock Maro Itoje with his knee on the throat of stricken Bok centre Damian de Allende, while home scrumhalf Faf de Klerk got away with what appeared to be a dangerous 'no arms' tackle on Murray.

World Rugby have confirmed that, aside from Sinckler, no other players have been cited.

"Following a full review of the match, there are no additional citings," their statement said.
