Natus Vincere star Aleksandr "s1mple" Kostyliev will fill in for mousesports in Thursday's ECS matches against Virtus.pro, the StarSeries i-League Season 4 champions have announced.
The Ukrainian talent will replace Martin "STYKO" Styk, who will sit out this pair of fixtures after his doctor advised him to rest.
This is not the first time that mousesports have turned to Aleksandr "s1mple" Kostyliev to secure a last-minute stand-in. In December, the 20-year-old replaced Tomáš "oskar" Šťastný in the semi-finals and the final of LOOT.BET Cup 2 - cs_summit 2 qualifier.
STYKO will be hoping to get back into shape quickly as mousesports prepare for DreamHack Masters Marseille, which will kick off in a week's time. The European mixture have been drawn in Group B, alongside SK, NiP and Valiance.
