RANGERS and Celtic's call to lock out away fans so far this season has been challenged by two fellow Premiership clubs, according to a report. 

Hearts and Motherwell are believed to be seeking answers from the SPFL.

Both sides of the Old Firm have cited red zone Covid restrictions as the main reason behind their decisions.  

This has resulted in the need to move season ticket holders into the traditional away sections in Ibrox and Celtic Park - meaning there is no room available to host travelling supporters.

But Hearts and Motherwell aren’t happy with that stance and have now written to the SPFL about the matter, according to the Daily Mail.

The high-flying duo say it's time to let away fans in to all games.

The report claims the Jambos will lodge a formal complaint to the SPFL board if they don’t get a satisfactory answer ahead of their trip to Ibrox on October 16.

Clubs have to traditionally provide a reasonable number of seats for travelling fans according to the SPFL rules.

That requirement was lowered at the start of the season due to Covid restrictions.

Hearts and Motherwell feel away fans should be allowed back in to Ibrox and Celtic Park.

Rule I27 of the SPFL regulations state: “Home clubs must make provision for the admission of such reasonable number of visiting supporters at every home league match and play-off match as may be agreed in advance with the visiting club and, in the event of their being unable to agree such number not later than 14 days prior to the date of the league match or play-off match in question, the number of visiting supporters allowed shall be determined by the Board whose decision shall be final and binding.”
