Talks over a new three-year contract began in January 2011, which went unresolved after the sacking of manager Andy Scott and the appointment of interim manager Nicky Forster a matter of weeks later. Injury problems meant that Osborne was in and out of the team under new manager Uwe Rösler during the 2011–12 season and he made just 27 appearances. In a U-turn, he rejected a new contract and was released in June 2012. In eight seasons at Griffin Park, Osborne made 185 appearances and scored six goals.
