ATHENS, Greece (AP) -- Panathinaikos ended Olympiakos' 27-match unbeaten league run on Sunday with a 3-0 away victory that was interrupted by home fans who threw flares and other objects onto the pitch.
Panathinaikos coach Yiannis Anastasiou was hit in the face by a plastic bottle and very little football was played in the last 12 minutes due to the missile-throwing after Olympiakos was awarded a penalty.
Alejandro Dominguez missed the spotkick and the referee didn't make up for time lost.
In a separate incident, Olympiakos' Michael Olaitan was taken to hospital for checks after collapsing. He was conscious when taken off on a stretcher.
Marcus Berg, Danijel Pranjic and Mehdi Abeid scored for Panathinaikos.
Olympiakos has a 19-point lead over Atromitos, a 3-1 winner at Panetolikos, and PAOK, which drew 2-2 at Ergotelis.
