Rotherham United have extended the loan spell of Notts County defender Jon Harley until January.
The 32-year-old has enjoyed a fruitful first month at the Don Valley Stadium, making five appearances.
Millers manager Andy Scott told
BBC Radio Sheffield:
"He's been a terrific signing for us. He goes about his business very well."
Harley and fellow loanee Guy Branston are not available for the FA Cup first round tie at Barrow on Saturday.
