Call it a game of musical bassists.

Original bassist Duff McKagan will reunite this month with the Guns N' Roses during their tour through South America, while current bassist Tommy Stinson drops in for a short stint with his former Replacements bandmates, Rolling Stones reports.

On Monday, McKagan hinted to the reunion via Twitter: "Argentina, Paraguay, Bolivia, Brazil! See y'all in the next few weeks, Si? GNR."

Stinson, who reportedly will return to Guns for the May 13 concert in Bethlehem, Pa., told Billboard he thanked McKagan for "covering my (expletive) on this one."

Stinson said he didn't want to leave the band in a lurch. "Luckily someone was able to reach out to Duff and he was amenable to the idea and was into doing it," Stinson added. "It's Duff being the kind of good sport he is, trying to help Axl (Rose) out."

It hardly sounds like a bad deal for McKagan either. "It's pretty great to play these songs again, and (I'm) looking forward to playing some gigs with my pal again," he told Rolling Stones.

McKagan played with the band from 1985 to 1997 and rejoined the group for their 2008 Chinese Democracy album. He also has played certain tracks with various members of the band in subsequent years.
