The San Francisco District Attorney's office is still deciding whether to file charges against a man police said put an Irish football player into a coma one year ago.

Mark McGovern, a Gaelic football player, recently walked the same field where he nearly lost his life one year ago.

McGovern recalled the moments leading up to his alleged assault on June 25 during a Gaelic football match on Treasure Island.

"He was just constantly hitting me in the ribs and everywhere I turned he'd be there," McGovern said.

A video from that day showed that the ball was at the other end of the field -- nowhere near McGovern -- when police said he was hit by a player on the opposite team.

Witnesses said Patrick Power of Half Moon Bay was standing over McGovern while he was down on the ground and said, "You won't get up from that."

So far, no one has actually said they saw the attack, or at least they aren't telling police about it.

The Irish-born athlete suffered a traumatic brain injury and slipped into a month-long coma.

His entire family flew out from Ireland to be by his bedside.

It took months for McGovern to learn how to walk and talk again.

In the meantime, the Gaelic Athletic Association suspended Power from playing for 96-weeks.

Police arrested him last September on suspicion of felony battery, but he was later released and no charges have been filed.

San Francisco District Attorney George Gascon said the case is still pending and he has two more years to decide whether or not to prosecute.

The district attorney released a statement to KTVU saying, "We encourage anyone with information to please come forward and contact the San Francisco police department."

Meanwhile, McGovern struggles with his speech and has been forced to give up his dream job in environmental planning.

"(My) brain's just not smart enough to carry out such education," McGovern said.

He has dizzy spells, and said he's prone to anger and has trouble concentrating.

Doctors told McGovern he can never play football again because the risk of injury is too high.

McGovern said he's still dedicated to the sport and plans to coach but said his life has been forever changed.
