The Czech soccer federation began investigating alleged Nazi salutes by Sparta Prague midfielder Pavel Horvath during a league match.
Federation spokesman Vit Pavlusek said Horvath's conduct was judged "unsportsmanlike," according to initial findings Thursday by the federation's disciplinary committee.
Horvath allegedly twice saluted Sparta fans with his right arm outstretched seconds before the end of the match against Viktoria Zizkov on Saturday, which Sparta won 4-1. Horvath was already substituted at the time.
The committee resumes its investigation next Thursday. Pavlusek said the federation also asked for TV footage of the incident.
