British and Irish Lions prop Kyle Sinckler has been cited for an alleged bite in his side's second test defeat to the Springboks on Sunday.
According to World Rugby, the alleged incident took place in the 64th minute of South Africa's 27-9 victory over the Lions.
The Englishman faces a minimum 12-week ban if found guilty.
Sinckler's citing comes after Lions teammate Stuart Hogg denied accusations of biting Willie le Roux that were leveled at him on social media.
Video footage circulating on various social networks appears to show the Scotland fullback biting opposite number le Roux on the arm, though the footage is inconclusive. Le Roux seems to immediately turn to referee Ben O'Keeffe to complain.
