Immediately after Stevenage shocked Newcastle United in the FA Cup with a 3-1 win Saturday, Stevenage defender Scott Laird was punched in the face by a soccer fan who ran on to the pitch at Broadhall Way.

It’s not known whether the person who punched Laird was a Newcastle United or Stevenage supporter.

“It is a shame for the afternoon to end in that way,” Stevenage manager Graham Westley said. “He is a bit bewildered. He gave him a right-hander, just smashed him across the cheek and knocked him to the ground. He said to me, ‘It’s lucky I’ve got a big head to take it.’ It was a sad way for things to end.”

The FA will investigate the incident.
