Celtic are set to announce the signing of Kris Commons after the Scotland winger finalised his move to Parkhead.
It is understood that Commons has agreed a three-and-half year deal.
The 27-year-old completed a medical at Ross Hall Hospital on Thursday after Celtic had a bid believed to be in the region of £300,000 accepted by Derby on Wednesday.
Rangers manager Walter Smith had confirmed his interest in the player on Tuesday amid talks between his club and County, but the debt-hit Ibrox club lack the financial muscle to compete with their Old Firm rivals.
Commons was out of contract at Pride Park in the summer and had failed to sign a new deal despite lengthy negotiations.
He will now join former Nottingham Forest team-mate Neil Lennon's squad ahead of the Co-operative Insurance Cup semi-final against Aberdeen on Saturday.
