James Featherstone, who represents Sheffield Wednesday manager Garry Monk and former Manchester United defender Chris Smalling and current, allegedly attacked businessman Darrin Bloomfield in the gents' toilets at the Stamford Arms in Bowdon, Cheshire.
Featherstone, 39, appeared in the dock at Manchester Magistrates' Court on Tuesday morning alongside his co-accused, Benjamin Cowgill, 38.
Both are charged with a single count of malicious wounding with intent to do grievous bodily harm to Mr Bloomfield on March 8 this year.
Neither defendant entered a plea during the hearing, which lasted less than two minutes, and magistrates sent the case to Minshull Street Crown Court, Manchester, for a further hearing on December 3.
Featherstone, of Two Gates, Oldfield Road, Altrincham, and Cowgill, of Stanhope Road, Bowdon, were granted unconditional bail until the hearing next month.
