Leeds Rhinos’ Australian forward Brett Delaney is facing a spell on the sidelines.
Scans have confirmed Delaney suffered a dislocated kneecap in last Saturday’s 62-6 win at Featherstone Rovers in the First Utility Qualifiers.
There was also some internal damage to the knee.
The 30-year-old will not require surgery, but it is not yet known how long he will be out of action.
Meanwhile, Rhinos’ middle-eights rivals Huddersfield Giants will be without half-back Danny Brough for the next two games.
Brough pleaded guilty to grade C striking with an elbow in last weekend’s defeat at Salford Red Devils and was suspended for two matches.
He will miss Sunday’s home game against Featherstone Rovers and the following week’s trip to Batley Bulldogs.
Meanwhile Hunslet Hawks’ star hooker Jack Lee has agreed a two-year contract extension with the club until the end of the 2018 season.
Lee originally joined the club from York City Knights on a two-year deal in 2015. He arrived in South Leeds with a big reputation after being awarded the Championship 1 player of the year award in 2014 and was Hunslet’s leading try scorer in 2015 scoring 13 tries. He has now made 46 appearances and scored 20 tries.
Hawks’ director of rugby, Darren Williams, said: “I am delighted that Jack has committed his future to the club. He had offers from other clubs for next season, but he has decided to re-sign, stating that the main reason was the culture and feel good factor at the club at present.
“Jack has been a massive player for us since he joined, and he will play an integral part of the clubs future, as we look to build a squad around him.
“We are looking forward to seeing him lead us forward for the remainder of the Kingstone Press League 1 Super 8s and for the next two seasons.”
