Chalmers spent a night in the cells and was fined after being arrested for a breach of the piece at showpiece event on April 10.

The former Scotland fly-half was facing charges that he acted towards a match official in an “abusive, insulting, intimidating or offensive manner” but despite being exonerated from those accusations he has been warned over his future conduct.

A Scottish rugby statement stated: “The panel heard from nine witnesses whose evidence did not paint a consistent picture of the facts and circumstances surrounding the alleged incident.

“Chalmers has been warned as to his future conduct and asked to ensure that, as a senior member of the Borders rugby community, he seeks to ensure good relations exist towards match officials.”

However, centre Jamie Murray was found guilty of the same accusation and has been suspended for three weeks.
