Das Silva fired the visitors ahead two minutes before the break and Hao Phat Ha Noi looked on course to pick up just their second win of the season until Duc struck with seven minutes remaining.

Defending champions Dong Tam Long shared a goalless draw with Song Lam Nghe in Saturday's other fixture.

Binh Duong hold a one point lead over second-placed Da Nang, who face Ha Noi on Sunday, while Hao Phat Ha Noi move above Dong Thap into 13th place.

Dong Tam Long remain eighth, while Song Lam Nghe stay 11th in the standings after eight games.
