PITTSFIELD, N.H. (AP) – The Pittsfield Middle High School soccer team or the school’s entire sports program could be punished after a player broke a rival’s leg during a championship game.

Three Pittsfield players and one Lisbon player were ejected from Sunday’s Class S championship game Sunday.

The game, which Lisbon won 3-0, was called off with 12:16 remaining after a Pittsfield player kicked a Lisbon player so hard he fractured two bones in his leg. Officials also are investigating reports that a Pittsfield player had to be physically restrained by his teammates as he swore at a referee and that fans jeered as the injured player waited for an ambulance.

“Even when the young man was hurt, he was being taunted by some of the fans,” said Patrick Corbin, executive director of the New Hampshire Interscholastic Athletic Association. “It was probably the lowest point of my career in terms of seeing inappropriate behavior and just poor sportsmanship.”

Corbin said possible sanctions include probation or suspension. The first would ban the team or school from participating in sports for one year, while the second would bar the team or school from the association indefinitely.

He said the association’s Sportsmanship Committee will hold a hearing on the matter after he reviews incident reports from the referee and each school.

Corbin attended the game, in part because a fight had broken out between players at last year’s championship game between Pittsfield and Woodsville High School.

Pittsfield’s Antonio Bifsha, who was ejected from last year’s game for fighting, received a yellow card Sunday and later was ejected after kicking Kyle Fifield.

Fifield underwent surgery Sunday night to have a rod inserted in his leg and faces more surgery Thursday, his mother said. Carrie Fifield also said her son has sustained some nerve damage to his foot and has been fighting a fever, which could indicate an infection.

She said Bifsha shouldn’t have been allowed to continue playing after being given a yellow card.

Pittsfield Principal Karen Erlander said the school would begin its own investigation. She was in the stands Sunday and said she spoke with some adults who were making inappropriate comments and asked students to behave better as the match became more aggressive.

“It doesn’t matter how skilled you are, it doesn’t matter how many games you win,” said Erlander, who noted that the team has been working for months to improve sportsmanship. “If your sportsmanship is unacceptable, you’ll find yourself sitting on the bench.”

In letters to the Concord Monitor, some Pittsfield students and fans lashed out at the game officials, accusing them of bias and saying they were equally to blame for the outcome. An apparent error by the referee led to the replay of 11:15 of game time because Pittsfield had been down a player.
