[3] Montgomery made his debut for Rotherham as a late substitute against Crystal Palace, coming on after Pollitt had been sent off for handball outside of his area.
[4] His second appearance came 10 days later in similar and dramatic circumstances; Rotherham were playing Arsenal in the League Cup at Highbury when Pollitt was sent off again in extra time.
He saved efforts from Sylvain Wiltord and Quincy Owusu-Abeyie, and even scored a penalty himself, however Arsenal ultimately triumphed 9–8 on spot kicks.
[6] Montgomery briefly returned to football during the 2010–11 season with Conference North side Boston United, but left the club in December 2010.
Montgomery appeared several times for Lancashire County Cricket Club 2nd Eleven, and signed a professional contract for the 2010 season.
