Tottenham fan Ashley Mills was left fighting for his life last week after he was stabbed on the eve of his team's Europa League game against Lazio in the Italian capital.
The 25-year-old was stabbed in the leg and also suffered a serious head injury after being caught up in a vicious attack on an American pub by up to 50 masked thugs.
Lazio insist their fans were not behind the attack and two supporters of the club's rivals Roma have since been charged with attempted murder.
The Biancocelesti tried to distance themselves further from last Thursday's events by today revealing their players will wear shirts with "NO RACISM" emblazoned across the front in large white letters during Tuesday night's game.
The Italian club posted a link to the picture of the shirt on their Twitter page along with the following message: "S.S. Lazio against all forms of racism! This is the jersey that the players will wear against Udinese."
Lazio president Claudio Lotito is reported to have visited Mills in hospital on Monday.
