Match ends, Northern Ireland 1, Bosnia and Herzegovina 2.
Northern Ireland made a disapppointing start to their inaugural Nations League campaign as they lost 2-1 to Bosnia-Herzegovina at Windsor Park.
The hosts dominated but fell behind to Haris Duljevic's 36th-minute close-range flick from Edin Dzeko's cross.
Elvis Saric slotted into the empty net after a mix-up between defender Craig Cathcart and goalkeeper Bailey Peacock-Farrell on 64 minutes.
Substitute Will Grigg hooked in a consolation goal in injury-time.
Northern Ireland were on top for large periods of the game, orchestrating wave after wave of attacks, but passed up a series of goalscoring opportunities and it was the visitors who proved more clinical.
The defeat deals a major blow to NI's hopes of success in the new competition which aims to eliminate the number of friendlies played in favour of more competitive games.
Bosnia-Herzegovina host Austria in their next fixture in Group B3, while NI manager Michael O'Neill is expected to take advantage of the opportunity for some experimentation when his side face Israel in Belfast on Tuesday.
The men in green then face a difficult double-header away to Austria and Bosnia-Herzegovina in mid-October, before a friendly with the Republic of Ireland and then their final Nations League match at home to Austria in November.
