Blink-182 -- Travis Barker Needs Time to 'Mourn'

Blink-182 just announced they're rescheduling two concerts -- they canceled last night's show -- because Travis Barker needs time to "mourn" DJ AM's death.

The following statement was posted on blink-182's website:

"After much thought and consideration, blink-182 has rescheduled their next two shows in order for Travis Barker to mourn the loss of his dear friend Adam Goldstein ... Travis, Mark and Tom would like to thank all their fans for their support during this difficult time."

ALSO: We've learned DJ Jazzy Jeff will fill-in for DJ AM this Friday at Rain Nightclub at the Palms Casino Resort in Las Vegas.
