A spokesperson for Tan Tock Seng Hospital said the 60-year-old remains unconscious, but his condition 'has not deteriorated yet'.
Dollah, one of Singapore's most recognisable football legends, collapsed at half time after playing just 10 minutes of the first half for a Singapore Veterans side.
He underwent an emergency angioplasty on Sunday night to clear up a blocked artery leading to his heart.
Families and friends, including his son and daughter, are currently keeping vigil at the hospital.
Said Dollah's former national teammate, Quah Kim Song, who is also the director of competitions at the Football Association of Singapore (FAS): 'The next 24 hours will be very telling. We are all praying for him.' - nst singapore
