YORK City Knights have announced that St Helens hooker Aaron Smith has extended his loan spell on a week-by-week basis.

Smith who initially joined from the Super League leaders on a month-long deal, will be in contention for Sunday's home game against West Wales Raiders.

Held in high regard by his parent club, the England Under-18 international has already proved valuable to Knights, scoring two tries in the win over London Skolars at Bootham Crescent and starring in the win at Doncaster.

Speaking to the club's website, 21-year-old Smith said: “I’m really happy to be back here on a week-to-week basis.

“I’m really enjoying my time at York. I’m learning a lot from experienced members of the squad such as Andy Ellis.

“Hopefully I can get back on the field and get a few more wins with this great team.”

Saints' assistant coach Paul Wellens hailed the "mutually-beneficial relationship" between the clubs while the Knights' head coach James Ford has expressed his happiness at being able to keep hold of the exciting youngster.

He told Knights' website: “I’m pleased to retain Aaron. He’s clearly a player that has plenty of potential - he needs to continue to work hard and ensure he maximises this.

“It’s very positive for the club that another top Super League club trust us with facilitating the development of one of their up-and-coming players.”
