Fulham says Wednesday's game with Liverpool may be postponed as a result of strike action by London Underground staff.
Tube workers have planned a 48-hour walkout for 21:00 GMT on Tuesday, reportedly throwing some midweek games in the capital into doubt.
The Londoners are concerned about the ability of their safety staff to get to Craven Cottage, with another announcement set to be made Tuesday.
"Following a number of enquiries regarding how the potential London Underground strike action may affect Wednesday evening's fixture against Liverpool, the club can confirm that it is currently proceeding on the basis that the game will go ahead," a Fulham club statement read.
"However, the club has concerns over the potential impact that the strike may have on the ability of its safety staff to attend the ground in sufficient time and numbers to ensure that it is able to open the ground and effectively operate it, from the time that the gates are open to the public until the departure of all supporters," the statement continued.
"After consulting with the Local Authority and the Metropolitan Police, it has been decided that, if the proposed action is still undetermined at 15:00 GMT [on Tuesday] and the club cannot guarantee enough staff are available to attend the ground in sufficient time and numbers, then as a consequence the club would not be able to comply with the terms of its safety certificate and the fixture would be postponed and rescheduled for a future date.
"A further statement will be released at 15.00GMT [on Tuesday] to confirm whether the game will go ahead or be postponed."
"We will inform supporters through our official channels as soon as more information becomes available regarding the fixture," a Liverpool spokesperson added. "The safety and well-being of supporters has to be the paramount concern of everyone involved in this process."
