Khairul Amri had originally been slated to stay for a longer period with Persiba Balikpapan. Prior to the match that caused his knee injury, the management team had proposed a contract extension to him. However, he had told the staff to wait until the end of the game. The injury however, proved a serious issue as the club could not afford to keep Khairul Amri on the sidelines for an extended period of time. During his recovery from the knee injury, Khairul Amri spent his time recuperating with Gombak United, at the offer of club chairman John Yap.
