British and Irish Lions full-back Stuart Hogg has denied biting South Africa's Willie Le Roux and says he is "annoyed and upset" by the allegations.
Footage emerged on Saturday of Hogg clashing with opposite number Le Roux during the Lions' contentious 27-9 loss to the world champions in Cape Town.
The coming together occurred following Cheslin Kolbe's tackle in the air on Conor Murray, with Hogg pressing his face against Le Roux's arm in the scuffle that ensued before being pushed away.
That was one of a number of heated incidents in the ill-tempered contest, which saw South Africa level the three-match series at 1-1 to set up a decider next week.
Citing commissioner Scott Nowland has yet to rule on the clash between Hogg and Le Roux, but the Scotland captain has denied any wrongdoing.
"Following speculation that has surfaced online, I would like to categorically deny any foul play in last night's game," Hogg said in a statement issued by the Lions on Sunday.
"I would never bite an opponent and I am annoyed and upset by this unsubstantiated accusation. I've always been proud of playing rugby in the spirit of the game.
"Respect to the Springboks for their deserved win. The squad is hurting after last night's defeat, but it's all to play for next week.
"It's going to be a cup final and everyone's going to be up for it."
