The Mail on Sunday says Gerrard and Carragher have been told they will have to give evidence in person in a case brought by Trading Standards against sports memorabilia company Sporting Icons.
The firm is accused of falsely claiming that the signatures on shirts and other items they have sold are those of the Liverpool pair and other sporting stars. Graeme Walker and former business partner Faz Madani deny 106 specimen charges under the Trades Descriptions Act. Walker also denies theft.
The case is due to begin at Chester Crown Court on Tuesday. Carragher, Gerrard and the club claim they had been led to be believe that only written submissions were needed.
A key date in the case may be March 11, when Liverpool will be in Milan for the second leg of their Champions League tie against Inter.
