Sharks forward Wade Graham was penalised for pushing Nofoaluma in the face midway through the first half, but got up complaining to referee Gavin Morris that he'd been bitten on the face.
Graham pointed to his mouth and remonstrated with the referee, before Morris acknowledged that the complaint was on the record.
Television replays were inconclusive, but if the match review committee find there is something in the incident, Nofoaluma can expect a long stint on the sidelines.
Canterbury prop James Graham was suspended for 12 matches for biting Melbourne fullback Billy Slater's ear in the 2012 grand final.
Tigers skipper Farah set-up the go-ahead try for Tigers centre Chris Lawrence in the 57th minute with a sharp dummy-half run, and looks right to go for NSW on May 28 in State of Origin I in a successful return from the elbow he dislocated in round six.
In another positive boost for Blues coach Laurie Daley, Farah's counterpart and NSW captain Gallen delivered a monster performance for Cronulla.
Twelve penalties were blown in the first half, as both sides showed they were more interested in niggle than discipline.
Tries to Nofoaluma and Pat Richards saw the Tigers to the break with a 10-8 lead, but Cronulla broke the game open after halftime when a short-ball from Todd Carney in his return from a hamstring problem, put a rampaging Gallen over.
Gallen was involved again two and a half minutes later when he popped a ball to a flying Gordon, although replays suggested the play should have been called back for a forward pass.
The Tigers refound their mojo when Brooks put back-rower Cory Paterson through a yawning gap to slash the margin to four and after Lawrence crossed, Wests held on for 23 minutes.
