The 31 year old winger has made three starts (in 13 appearances) this season on loan from Blackburn.
Feeney was originally signed until January but that has been extended until the end of the season. He is eligable to face Mansfield at CCS in the FA Cup on Saturday.
Feeney adds a body to the squad but to be fair he hasn't added much to City's attacking options. He needs to improve to justify the faith placed in him by Neil Warnock.
