Coid was injured just before the start of the 2009–10 season, and by October 2009 had started light training with the hope that by the end of November he would be playing a full part in training sessions. His aim being to be playing again for "the Seasiders" by Christmas. Coid had suffered a fractured tibia and a strained hamstring. He finally made his return to action, and his first appearance of the season, on 3 February 2010 in the 2–3 home defeat to West Bromwich Albion, following an injury to regular right-back Neal Eardley and central defender Alex Baptiste falling ill prior to the game, meaning Coid was a late call-up to the squad and then the starting line-up. He played despite only a handful of training sessions since recovering from his injuries. However, he was forced out of the action at half-time after feeling his hamstring strain. He did not appear again for the club until 24 August 2010, when Blackpool – then of the Premier League – exited the League Cup at the hands of MK Dons.
