The Wales international was instead fined £5,000, with £4,000 of that suspended until May 30 next year.
His Sharks team-mate Tom Brady did not avoid suspension, however, after he was found guilty of a dangerous tackle on Ben Skirving during the 31-10 defeat. Brady was handed a two-week ban by an RFU Disciplinary Panel to leave the Sharks, bottom of the Aviva Premiership table, without the winger until October 16.
London Wasps prop Tim Payne has been suspended for two weeks after pleading guilty to a Rugby Football Union charge of striking with the knee.
The 33-year-old was cited for striking Northampton winger Vasily Artemyev during the Saints' 24-6 victory in the Aviva Premiership meeting between the two sides on September 28.
Wasps, who are currently 10th in the table with only one victory to their name so far this season, will now be without Payne until his suspension ends on October 15, meaning he misses the league fixture against Worcester and the Amlin Challenge Cup clash with Newport Gwent Dragons.
