Mark Percival has been forced off the field in St Helens’ Challenge Cup clash with Hull FC.

The centre was tackled by Brad Fash with the Hull FC forward landing on his head.

Fash’s arm and shoulder landed straight on Percival’s head as it collided with the ground effectively creating a sandwich where Percival’s head was the meat.

Fash was placed on report and St Helens took the two to take their lead out to 8-0.

They led 6-0 after a short Jack Welsby pass saw Joe Batchelor slice through and score.

There was contact with the head and some may feel like it could have carded.

Evening things out, Hull FC have lost Scott Taylor to injury and Saints have shown they can produce big hits of their own with Curtis Sironen smashing Davy Litten.

Hull have hit back with a lovely try since this incident.

Tex Hoy carved through and found Josh Griffin in support to score and make it 8-6 after former Leeds Rhinos star Liam Sutcliffe nailed the conversion.
