Cardiff City midfielder Tommy O’Sullivan has extended his loan spell at Vale Park until the end of the season.
O’Sullivan has made one start and two sub appearances since joining Vale.
Manager Rob Page told the official website: “It’s great to have sorted out a deal that will keep Tommy here until the end of the season.
“He’s a terrific lad and a really promising player and I’m sure he will help us get to where we want to be between now and when the campaign finishes in a few weeks time.”
O’Sullivan added: “It’s been good experience for me training and playing with first team players and League One standard so hopefully that can benefit me in my future as well.”
