It is becoming increasingly unlikely that Newcastle playmaker Brock Lamb will be playing for the Knights next season, after his manager revealed there is no deal being discussed between he and the club.

Newcastle have been on the look out for halfback options, following Jack Cogger's impending defection to the Bulldogs and now Lamb's likely departure, despite coach Nathan Brown having his backing.

Asked about Lamb's playing future over the weekend, his manager Gavin Orr was blunt.

“Personally, I can’t see him staying,” Orr told The Newcastle Herald. 

“At this stage, the Knights haven’t even made me a written offer for Brock as yet.

“All they have said is they probably can’t get to what I want [money-wise] and I’ve heard nothing further from them.

“As I said, I can’t see him staying but it will be up to Brock at the end of the day.”

Orr revealed he is currently in negotiations with four rival clubs about Lamb's services, who the Knights refused to give up prior to the June 30 transfer deadline due to being "short in the halves at the time", a Knights source told The Newcastle Herald. 

One club who was keen on picking up the 21-year-old was Manly, who ended up acquiring ex-Knights playmaker Trent Hodkinson from the Sharks.

Lamb has played eight games this season after featuring in 21 contests in 2017 and has struggled to regain his place in the side after fracturing his cheekbone against the Titans in round 8.
