After a brief return to work on Tuesday, G.O's medical issues have unfortunately worsened, causing MBLAQ to officially cancel further promo for their comeback single, "Mirror."
A spokesman for the group tells IdolWow! via statement, "G.O has been diagnosed with laryngitis and has been ordered to rest. The other members support him. Please wish G.O a healthy recovery."
"Mirror" was released on June 9 -- less than three weeks ago -- and has managed only 379,000 views on YouTube (at the time of posting). Their final appearance for the single was on Music Bank today (see video below), June 19, as well as an interview on MBC FM4U.
The news -- which was first broken by Korean outlet OBS -- is a major blow to the group, who have only just debuted as a trio after members Thunder and Lee Joon left in November 2014.
G.O's vocal issues first became known after he was rushed to hospital on June 11 following his throat closing up after an appearance on SBS Power FM's Cultwo Show. At the time it was reported that the 27-year-old suffered from polyps on his vocal chords.

He official returned to work on June 16 and even managed to lip-sync during appearances on SBS MTV's The Show and Arirang TV's Simply K-Pop.
Adds the rep, "MBLAQ will meet fans again when they release their next mini-album." Get well soon!
