24-year-old Tuka, although he participated in only one race of the Diamond League, in Monaco in July, where he won with the best season result (1:42.51) theoretically still has chances to be a total winner of the most prestigious athlete competition in the discipline 800 meters.
With the win in Monaco, Tuka won four points and took the fourth place in the overall standings, after the leader Nijel Amos from Botswana with 12 points. Second-placed David Rudisha from Kenia (6) and the third placed Hassan Suoleiman from Djibouti (5) will not perform in Brussels.
If Tuka win tonight in Brussels and Amos is not among the first three, our athlete would win new four points which will be doubled since it is about the finals.
12 athletes were registered for the race on 800 meters, and Tuka will have the biggest competitors in the Polish Kszczot, Ethiopian Aman, French Bosse and Morroccan Balhambelo.
The race on 800 meters in Brussels is on program tonight at 8.56 p.m.
