Doctors have ordered the drummer, who suffered from blood clots in his arms in June, not to perform on the band's upcoming autumn mini-tour, which was due to start at Riot Fest in Chicago, which takes place from September 14-16.
Blink wrote in a statement: ''It is with a heavy heart to report that blink must cancel its fall mini tour which was set to kick off September 12th on their way to headline Riot Fest in Chicago. Medical issues have sidelined Travis per doctors' orders. Trav's medical team anticipated he would be well enough by fall to tour but after recent checkups they were not able to clear him in time for the scheduled run of dates. (sic)''
Travis revealed doctors have told him the risks associated with drumming are ''too great'' for him to get back to his sticks for now, but he is doing ''everything'' he can to be able to tour again.
He added in a statement: ''The past few months have just sucked as I have been sidelined just waiting for my doctors to clear me so I could get back on the road and perform with my band. Unfortunately, the risks associated with drumming are still too great.
''I am doing everything I need to do so I can get back on the road as soon as possible. I want to thank my fans, family, friends and bandmates for all the love and support. (sic)''
The band are hoping to headline Riot Fest in 2019.
Blink were forced to postpone dates on their Las Vegas residency in June when Travis' doctor warned him not to perform after he suffered from blood clots in his arms, followed by a staph infection.
Travis said: ''I'm as good as I can be. I'm just following the doctor's orders. I actually had [a] staph infection and a ton of blood clots, and I've just been in a recovery period. So I'm just waiting for everything. I see doctors weekly.''
What's more, Travis was involved in a potentially tragic car crash in July when his vehicle was hit by a school bus, but he and his son, Landon Asher, 14, escaped unhurt.
