Natus Vincere are among the favourites to win season 15 of the ESL Pro League but will at least start the competition without captain Kirill "Boombl4" Mikhailov, who is unavailable for selection.
Punters can back Natus Vincere at 5/4 to win the ESL Pro League.
In the absence of "Boombl4", teenager Daniil "headtr1ck" Valitov is set to be promoted to the first team from NAVI Junior to take his place.
Natus Vincere were last in action back in February in the IEM Katowice, having reached the tournament's semi-finals in which they lost to G2 Esports.
They had won Group B in the tournament after victories over ENCE, FURIA Esports and FaZe Clan and were also crowned champions at the PGL Stockholm Major back in November last year.
