Derby defender Russell Anderson has left Derby after his contract was cancelled by mutual consent. His deal was due to expire at the end of the season but an agreement has been reached that his contract would be cancelled 6 months early. It is thought his current injury is so bad he would be out for the whole season. In his time at Derby he has had numerous injuries which has restricted him to playing under 35 appearances since joining in 2010. His former club Aberdeen are believed to be interested in offering him a contract.
