|Leeds United's controversial owner Massimo Cellino is attempting to prevent his side's Championship clash with Derby on Tuesday from being televised.|
Staff from Sky Sports were denied entry to Elland Road on Monday as they arrived to set up for the match.
Cellino, currently on a Christmas break at his home in Miami, is claimed to have threatened Leeds staff with disciplinary action if they allow any members of the Sky Sports team in.
The Italian businessman, who has courted controversy throughout his Leeds reign, believes live TV coverage undermines his club’s attendances and commercial income.
Leeds have already been shown nine times on Sky Sports this season, resulting in a number of kick-off and date changes.
A TV black-out would be embarrassing for the Football League, who are attempting to convince Cellino not to follow through with the ban.
"The League has been made aware that Sky personnel have been unable to access Elland Road today as previously arranged," a Football League spokesman said in a statement.
"We have contacted Leeds United to remind the club of its obligations to our broadcast partner and to ask them for their observations.
"As yet, we have not received a response from anyone in authority at the club, but are hopeful that the matter can be resolved swiftly once the club does engage."
Former Cagliari owner Cellino is currently waiting for an appeal date as he fights a second Football League ban for breaching its Owners' and Directors' test following a tax evasion conviction in Italy.
He will not be present at Elland Road on Tuesday and has left the enforcement of his ban with other staff.
