Current Guns N' Roses bassist Tommy Stinson has confirmed that founding member Duff McKagan will rejoin the band for a five-show tour of South America that begins this weekend.

Stinson, who needs the days off in order to reunite for a series of festival dates in North America with his former band, the Replacements, tells Billboard that McKagan is simply being a "good buddy" by filling in for him. The first show will be Sunday night April 6 in Buenos Aires, and the last on April 17 in Fortaleza, Brazil.

"I had those Replacement shows come up the same time the (South American) tour came up, and it got to be a scheduling issue right out of the gate... luckily someone was able to reach out to Duff and he was amenable to the idea and was into doing it. It's Duff being the kind of good sport he is, trying to help Axl (Rose) out."

McKagan, who played his last show as a full-time member of Guns N' Roses back in July of 1993, has rejoined his former band on stage before, including a visit at the London's 02 Arena in 2010 and at Seattle's Key Arena back in December of 2011.
