Mastodon were set to hit the road in two days with alt-rockers Dinosaur Jr., but now that tour has been scrapped.
Blabbermouth reports that the band announced the cancellation "due to a critical situation of a member of the Mastodon family."
Mastodon "would like to extend their sincerest thanks to their loyal fans as well as the fans of DINOSAUR JR. for their support and understanding at this time," the statement continues. "The band hopes to make up these shows at a future time, but as of now, no plans for rescheduling have been set. "
