Moses Usor was missing at the weekend when Slavia Prague returned to the 1. Liga after a successful Europa Conference League qualifying campaign.
Usor scored in the win against Rakow, but the young forward suffered a stiffness in his thigh and was subbed off before the end of the game.
Speaking after the game, the 20 year-old admitted he suffered cramps which forced his substitution.
While the Forward was not named in the matchday squad for Sunday’s league game against Brno, his compatriot, Peter Olayinka got the nod.
Olayinka made only his second league appearance in the away game at the ADAX INVEST Arena.
Slavia Prague will go on to win 4-0, taking their streak of victories to four games, since their opening day defeat to Hradec Kralove.
The red and whites top the league with 12 points after five round of matches – two points more than second placed Liberec.
