Collins gained a red card in Huddersfield's first match of 2009–10 away to Southend United on 8 August 2009. His first goal of the season came in the 65th minute of Huddersfield's 2–1 home victory over Yeovil Town on 29 August 2009. Collins was ruled out for the remainder of 2009–10 in April 2010, following surgery on a broken finger, but he returned as a substitute in the 2–1 defeat at Exeter City. He then came on as an 89th-minute substitute in the first leg of Huddersfield's play-off semi-final match with Millwall, and was an unused substitute in the second leg defeat at The Den on 18 May 2010. Collins made 35 appearances in 2009–10, scoring three goals. Along with seven other players, he was added to the transfer list by manager Lee Clark in May 2010.
