Dragons duo Scott Morgan and Aled Brew have been given the green light to face the Cardiff Blues by a Welsh Rugby Union disciplinary committee.
Morgan and Brew had been cited following the 23-11 victory over Glasgow at Rodney Parade.
Morgan, who arrived at Newport from the Blues, was accused of punching, with winger Brew called before the panel after being charged with a dangerous tackle on DTH van der Merwe.
A WRU statement read: "The allegation of a 'spear-tackle' [by Brew] was dismissed and although he was found guilty of a dangerous tackle, this offence is dealt with by awarding a penalty or handing the player a yellow card, it is not a red card offence so no further sanction is necessary.
"The case of Scott Morgan was for punching or striking an opponent. This citing was not upheld because the panel were not satisfied that the player struck the opponent and the player is free to play."
