The move fuels further speculation about the longtime players' participation in GNR's reunion tour, which to date has only confirmed the involvement of Axl Rose, Slash and Duff McKagan.

Keyboardist Reed has been in the GNR lineup since 1990, while guitarist Fortus has been on board since 2002. Guns N' Roses will launch the reunion run with a pair of shows at the new T-Mobile Arena in Las Vegas on April 8 and April 9 - just two days after the venue's opening on April 6.
