Walker is also trying to sign another player before the Salisbury game

York City have signed teenage trialist Tom Hirst after he impressed while playing for the club's reserve team during the week.

The 18-year-old right-back was an apprentice at Rotherham United and has also had a spell at Hull City.

Manager Colin Walker told BBC Radio York: "He's a breath of fresh air. He's young and he runs about.

"He is quick and I think he will add a lot of pressure to the other people in the team for a place."

Hirst is expected to be available for Saturday's game against Salisbury.
