Joey Barton has been found not guilty of assaulting then Barnsley manager Daniel Stendel.
Barton, now in charge of Bristol Rovers, was Fleetwood Town boss at the time of the incident at Oakwell in April 2019.
The former Premier League footballer was cleared at Sheffield Crown Court of pushing over Stendel in the tunnel at the end of a match, leaving him bloodied and with a broken tooth.
When Barton gave evidence last week, the 39-year-old denied it was him who shoved Stendel after a League One match between his Fleetwood team and the South Yorkshire side on April 13, 2019.
Mr Stendel told a jury how he was walking down the tunnel in the corner of Barnsley's Oakwell Stadium after his side's 4-2 victory when he was knocked over by a push from behind, causing him to hit his face on the metal structure.
Video footage shown repeatedly during the trial showed Mr Stendel entering the tunnel followed by Barton, jogging, a moment later.
The jury took under two hours to find Barton not guilty of one count of assault occasioning actual bodily harm following a week-long trial.
After leaving the court, Barton said: "I think the verdict speaks for itself." Asked how he felt, he said: "Better than I did before." He left the building with his solicitor, who said his client did not wish to comment.
The 10-person jury heard how the incident in the tunnel happened after a second half which featured tensions between the coaching staff of the two sides, with Fleetwood's assistant manager, Clint Hill, receiving a yellow card.
Jurors were shown mobile phone footage of the handshake between the two managers at the end of the match during which, Mr Stendel told the jury, Barton was aggressive towards him.
Barton admitted using "industrial language" during the handshake, but denied he was aggressive, and said there had not been tensions between the two managers during the match.
He explained that he had only tried to explain to Mr Stendel that, if they did not control their coaching staff, they might be personally liable to substantial fines from the league.
Barton pointed out that, after the handshake, he had a friendly chat with a Barnsley player about his time playing for the French team Marseille and also the referee, before he headed for the tunnel.
He said he began to jog because he wanted to get into the dressing room ahead of his players. He said the video footage showed him weaving through the crowded tunnel towards the stand.
Barton stood in the dock for the verdict wearing a dark suit over a white shirt with a dark tie.
He was immediately told he could leave the court by Judge Jeremy Richardson QC.
