Sky Sports News sources understand that Queens Park Rangers have bid for Watford star Danny Graham.
The striker was a revelation in the Championship in the 2010/11 campaign and finished as the division's top scorer with 24 goals.
Skysports.com revealed last week that Newcastle are showing an interest in Graham as Alan Pardew attempts to replace Andy Carroll.
But QPR, who will face Newcastle in the Premier League next season after winning the Championship, are understood to have made the first move by tabling a bid.
QPR manager Neil Warnock confirmed earlier on Thursday that planning was already well under way for the new campaign and that is likely to include transfer targets.
It has also been suggested that Warnock could be forced to wave goodbye to some of his key assets, but he insists that is not the case.
He told QPR's official website: "I've been given assurances that I won't have to sell my better players.
"I'm working hard behind the scenes in a bid to improve the squad ahead of the new campaign."
