Napoli midfielder Marek Hamsik will miss Thursday's Europa League encounter against Viktoria Plzen with flu.
The 25-year-old Slovakian was robbed at gunpoint on Sunday following his side's goalless draw with Sampdoria in Serie A.
He will now sit out the game in Prague through illness as the Italians look to overturn a 3-0 deficit in the second leg of their last-32 tie.
Hamsik has scored nine goals in 30 games for Napoli this season.
