Leeds Rhinos have given a three-year contract to part-time player Jimmy Keinhorst.

The 22-year-old centre, a Germany international who is starting his third year of a sports science degree at Leeds Metropolitan University, played in the Carnegie Challenge Cup final last month in only his fourth appearance for the Rhinos and made his first start in last Friday's Stobart Super League win over Salford City Reds.

"I am really happy to have signed a long-term contract with the club," he said.

"Studying at Leeds Met has been great for me and I definitely would not have got the chances I have had in rugby league without the close ties between the university and the Rhinos.

"I am going into my final year now and I know it is going to be tough but it is something the Rhinos are fully supportive of.

"I am excited about the opportunities I have at the Rhinos but I also want to finish with a strong degree after three years hard work so it will be a busy time."

Leeds coach Brian McDermott said: "Jimmy has impressed everyone at the club this season with his performances for the Under-20s and the first team and he deserves this new deal.

"For a 22-year-old to have played at Wembley in his fourth senior appearance is an incredible achievement and something that will stand him in good stead for years to come."
