Rival second-rowers Adam Byrnes and Will Caldwell have escaped suspension following citings in the aftermath of NSW's thrilling Super 14 victory over Queensland.

The pair fronted SANZAR judicial officer Paul Tully in Brisbane on Sunday after NSW's 30-28 win was marred by a biting allegation levelled at Byrnes by Caldwell in the first half at Suncorp Stadium.

Reds management also reported Caldwell post match for allegedly making contact with Byrnes' eye region.

Caldwell successfully argued his hand accidentally went across the face of Byrnes as he attempted to rip the ball from his possession midway through the first half.

The Reds lock was also exonerated after it was found Caldwell's finger accidentally entered Byrnes mouth and damage was consistent with it being ripped out rather than being bitten.

The Waratahs received mixed news from Sunday's three judicial hearings with back-rower Dean Mumm suspended for two weeks.

Mumm was found guilty of illegally charging into a ruck or maul without use of his arms after he pole-axed Reds replacement hooker Saia Faingaa from behind.

The ban will rub the blindside flanker out of NSW's two-match tour of South Africa but the Waratahs are considering an appeal, which must be lodged within 48 hours.
