The Times reports that the South African-born prop is still waiting for his visa application to be approved. Unlike those with UK passports, South African nationals require a tourist visa to enter Canada. McBeth's original visa appointment couldn't go ahead as he had picked up a concussion in Glasgow's URC quarter-final against Stormers.
McBeth spent Friday at the Canadian embassy in London with no success but he'll return on Monday to get the paperwork required to travel.
