The match review committee fined Daly Cherry-Evans $1000 on Sunday, clearing him to play the Dolphins in the preliminary final.
The decision followed a controversial incident during Friday night's NRL semi-final, when the Roosters led Cronulla 24-10 in the 60th minute.
Teig Wilton broke through and nearly scored, but the Bunker ruled he had made a double movement.
It also judged that Cherry-Evans deliberately tripped Wilton by extending his boot and reaching with his arms, calling the action "unnatural".
Although Cherry-Evans was penalised, he remained on the field despite deliberate tripping usually bringing a 10-minute sin-bin.
He then created tries for Mark Nawaqanitawase and Robert Toia during that period, helping the Roosters defeat Cronulla 46-10.
Cronulla had lost halfback Nicho Hynes to concussion in the opening set, yet stayed within 18-10 at half-time.
Sharks great Paul Gallen said the decision could have changed the contest.
"It was only 24-10 at that stage. If it goes 24-16 it could have been a much different game. The Sharks were dealt some adversity and that was another moment. Definitely should have been sent to the sin-bin without a doubt."
Gallen had predicted Cherry-Evans would receive only a fine, rather than a suspension, and the Grade 1 charge produced that outcome.
Roosters players Billy Smith and Lindsay Collins also received $1000 fines for separate Grade 1 offences.
Journalist Darren Walton criticised the ruling online: "Rugby league is a joke now. Cherry-Evans trips someone and is allowed to play on. Then throws a final pass for a try. The old days tripping was up there with spitting as a disgusting blight on the game. Now it's a 'slap on the wrist'."
