The Ice Valley rider crashed at the Black Dub and was taken to Liverpool Hospital after being assessed at Noble's Hospital. He recently had a drain in his head removed and his lungs have shown a slight improvement but remain a concern.
He also suffered multiple fractures in the crash, including his pelvis and ribs. Srdanov had made a stunning start to his debut TT posting a 113.80mph lap on his first ever night of practice last week. On Thursday evening practice the 25-year-old set a 120.112mph best.
