West Ham and Burnley have bids accepted for Hull City's Robert Snodgrass, Sky sources say.
West Ham, Burnley and Middlesbrough have all been bidding for the Scotland international since the transfer window opened, and the Clarets were successful with an offer of around £10m on Wednesday.
The Hammers responded by raising their own offer - a third - which was accepted by Hull later in the day.
Sky Sports News HQ understands Middlesbrough's current offer also totals £10m but is structured differently to the new bid from Burnley.
Snodgrass is Hull's top scorer this season, with nine goals in all competitions, and was on target in the 1-1 draw with Burnley at Turf Moor back in September.
Hull activated an option to extend the 29-year-old's contract in December, and his current deal is now due to expire in the summer of 2018.
The club's new head coach Marco Silva has been busy adding to his squad since his arrival in the first week of January and sources say the club are looking to bring in four or five additional new players before the window shuts.
Evandro Goebel has joined on a permanent deal from FC Porto, while Oumar Niasse and Omar Elabdellaoui have signed on loan from Everton and Olympiakos respectively.
And on Monday, Silva was able to complete the signing of winger Lazar Markovic from Liverpool on loan for the rest of the season.
They have also allowed Jake Livermore to join West Brom for a fee in the region of £10m, while goalkeeper Allan McGregor has signed for Cardiff on loan.
