Former Celtic defender handed career lifeline with unexpected transfer

The 34-year-old has been without a club since leaving Norwich City in the summer, having last made a competitive appearance in November 2025.

Duffy, who spent the 2020/21 campaign on loan at Celtic from Brighton, made 27 appearances during a difficult season at Parkhead before returning south.

The Republic of Ireland international subsequently joined Fulham before moving to Norwich in 2023, but has now been handed an opportunity to revive his career at Pride Park.

After impressing during a trial period, Duffy has signed an initial two-month contract as Derby look to address a growing list of defensive injuries.

A club statement confirmed: “Derby County have completed the signing of Shane Duffy on a short-term deal. The 34-year-old has penned an initial two-month contract in DE24 following a trial period with the club.

“Duffy adds extensive experience to the Rams’ defensive ranks, with the towering centre-back nearing 500 professional appearances across club and international football. At international level, Duffy has represented the Republic of Ireland 61 times – scoring seven goals – since his debut in 2014.

“The Irishman will be in available on Saturday when the Rams travel to Millwall (3pm kick-off).”
