Falkirk are trying to reach the last four for the first time since they won the trophy in 1957. Their manager, Alex Totten, said: "We've beaten Dunfermline at Brockville and it will take a similar performance if we're to get through against Raith."
Dundee United, unbeaten in 13 matches, face Motherwell at Tannadice in a repeat of the 1991 final. Motherwell won 4-3 on that occasion under the management of Tommy McLean, who is now in charge of United.
"We are favourites but I don't buy that," McLean said. "Motherwell have been having a hard time in recent weeks but there is a lot of glory attached to a good cup run and reaching the semi-finals."Reuse content
