Gareth Ellis has been cleared of any wrongdoing during Hull's 22-16 loss to Huddersfield Giants on Sunday afternoon.
The second-rower had been charged by the authorities for allegedly striking Luke Robinson at the KC Stadium.
He was provided the opportunity to lodge an early guilty plea, but the 32-year-old instead opted to challenge the verdict.
His decision was vindicated this evening when a disciplinary committee in Leeds cleared him of the offence.
As a result, the England international is free to play in Saturday's Challenge Cup quarter-final in Perpignan against the Catalans Dragons.
