At the start of the 2011–12 season, Keinan found himself not in the starting eleven, being replaced by Anthony Gerrard who returned from his loan spell at Hull City. He got his first call up to the team on 23 August against Huddersfield Town in the League Cup. Keinan didn't find himself on the bench until a start against Leicester City, on 21 September. Due to a mass of injuries, Keinan found his first league appearance under Malky Mackay against Southampton a week later. On 21 November 2011, Keinan joined Crystal Palace on a six-week loan after finding himself far down the pecking order.
