Shuker rarely featured in the first half of the 2013–14 campaign, but began to feature regularly as a substitute in January. Manager Micky Adams revealed Shuker had been absent from first team squad contention due to a chronic knee injury Shuker had been suffering with for years, but had become more serious with time to the point where his future as a footballer was in doubt. Shuker announced his retirement at the end of the season on account of the knee injury.
