Collingwood took his first Test wicket on 6 August 2006, trapping Faisal Iqbal leg before wicket for a golden duck in the Third Test at Headingley. During this series he also bowled a couple of overs of off-spin, to the surprise of many, including the commentary team on Test Match Special. Later that summer, he reached his 100th ODI cap and 50 ODI wickets in the same match by claiming the wickets of Inzamam-ul-Haq and Abdul Razzaq during the Fifth ODI against Pakistan in Birmingham on 10 September.
