The press commended Celtic for the way in which they had been prepared to play the re arranged Motherwell fixture rather than exploit the commercial potential of extending the season. They were also praised for having avoided midweek fixtures that could have had a negative effect on the war effort by causing absenteeism from industries.
The Celtic team that turned out in the evening match had only one change from the afternoon game -Joe O’Kane, who had scored 2 against Raith Rovers, gave way to Trooper Joe Cassidy, who had missed the Raith game having arrived late from Perth barracks where he was serving in the army. The other ten were:
Charlie Shaw, Alec McNair, Tom McGregor, Sunny Jim Young,
Joe Dodds, Johnny McMaster, Andy McAtee, Patsy Gallacher, Jimmy McMenemy and Johnny
Browning.
Motherwell themselves made only 3 changes. The attendance at the evening game was 10,000. equaling Celtics afternoon gate but doubling Motherwell's.

At the time of the 2 games in a day Celtic were on a 62-game unbeaten run that extended from 13.11.15 until 21.04.17.
