MxPx have dropped off their scheduled supporting run with Yellowcard. The band explained:

We're sorry report that due to scheduling conflicts we've had to pull off of the US tour with Yellowcard. We will definitely be in Australia as planned and we WILL be making a US tour announcement ASAP, so watch our sites! The shows in Japan were awesome as was our first ever visit to Indonesia.

The long–running punk band released Secret Weapon last year.
