Cardiff chairman Peter Ridsdale has confirmed the club have agreed a fee in the region of £300,000 with Motherwell for full-back Paul Quinn.
Ridsdale told the Daily Record: "The situation is we have agreed a fee with Motherwell and we expect the lad down to discuss personal terms in the next 24 hours."
The move could complete a busy period of trading for the Bluebirds. Centre-backs Mark Hudson and Anthony Gerrard have signed in the last couple of days.
