Steven Reid has joined Burnley on a free transfer to become the promoted club's fifth summer signing.
The 33-year-old, who was released by West Bromwich Albion at the end of last season, has signed a one-year contract at Turf Moor.
Reid was a teammate of Burnley manager Sean Dyche during his time at Millwall and has also played for Blackburn and QPR as well as winning 23 caps for the Republic of Ireland.
He spent much of his career in midfield, but was used by Albion as a right-back and could provide competition for Kieran Trippier.
Burnley's second-choice right-back Chris Baird has made the opposite move to Reid, joining West Brom on a free transfer.
Burnley brought in West Ham's Matt Taylor and Bolton's Marvin Sordell on Friday, to follow earlier deals for Stoke winger Michael Kightly and Blackpool goalkeeper Matt Gilks.
All four, like Reid, have previously played in the Premier League and manager Dyche said he was keen to add players with a background in the top flight.
He told Burnley's official website: "Steven is a very strong minded professional and he has had years in the Premier League so he has that bit of experience and know how.
"I know him personally from his younger days at Millwall and he was a very solid pro then and he still is now, perhaps a more rounded version of what he was then.
"Along with Matty Taylor we want that experience in the building as well as the vibrancy in the team.
"Both of those players played in some really awkward games for West Brom and West Ham respectively and hopefully that experience can rub off on others."
