Experienced centre-back Shane Duffy has joined Championship side Derby County on a free transfer following his release from Norwich City in the summer.

The 34-year-old joins on a two-month deal after impressing during a trial with the club and will be available for the Rams' trip to Millwall on Saturday.

The defender has made more than 500 appearances for club and country, earning 61 caps for the Republic of Ireland and scoring seven goals. However, he has not featured for the national side since 2024.

Duffy spent six years at Brighton & Hove Albion between 2016 and 2022, helping the Seagulls secure promotion to the Premier League in 2017.

He has also had spells at Blackburn Rovers, Celtic and Norwich City, where he made 91 appearances and scored five goals.
