Lions prop Graham Rowntree and Auckland centre Sam Tuitupou have been cited for separate incidents in yesterday's match. Auckland officials claim Rowntree struck lock Bryce Williams in the first minute of the game, which featured several fights.
Rowntree, 34, made his Lions Test debut as a replacement in Saturday's 48-18 defeat, and any ban at the disciplinary hearing in Eden Park today would rule him out of Saturday's third and final Test.
Tuitupou has been cited for an alleged stamp on Lions centre Gordon D'Arcy early in the second half.
The centre was also involved in a first-half exchange of blows with Lions lock Ben Kay, which led to Kay leaving the pitch with a black eye, although match officials ruled, wrongly, at the time that the Englishman had thrown the first punch.
The disciplinary hearing will be conducted at Eden Park by the IRB's judicial officer Terry Willis - the same official who suspended Danny Grewcock for two months after the Lions lock was found guilty of biting Keven Mealamu in the first Test.
