The Scottish Premier League (SPL) faces a challenging weekend after Polish replacements for striking referees pulled out.

Category one referees initiated the strike claiming they were getting too much abuse from players.

Eleven of the 20 fixtures, including all six SPL matches, were still due to go ahead but with referees from Poland, Portugal and Israel standing in.

The Polish withdrawal creates further headachs, as the Scottish Football Assocation will now be forced to scramble and find additional cover.

Some foreign associations – including Ireland, Wales, Norway and Sweden – have already rejected approaches to provide officials.

“We will not be sending our referees to Scotland tomorrow because they are needed for our domestic games,” confirmed Poland’s FA in a statement.

“We did confirm to the SFA yesterday that we would be sending a team of 12 officials but that is no longer the case.
