After failing to agree terms for Ross McCormack, Boro have gone back for Blackburn striker
Boro made McCormack their number one target in January - but with Fulham under a transfer embargo and not able to sign a replacement, they have repelled the advances from the Teessiders.
Middlesbrough boss Aitor Karanka has made it clear to his bosses that he needed a new number 10 and a striker, and with Gaston Ramirez already signed - they turned all their attentions to a new front-man.
With McCormack always looking difficult, Boro always kept lines of communication with Blackburn open and now they have made their move - with the deadline fast approaching on Monday.
HITC Sport understands that the deal for Rhodes has been agreed in principle and the player is highly unlikely to feature in their FA Cup clash with Oxford - indeed he could very well be on Teesside as early as Saturday morning.
Middlesbrough know Rhodes well, with his uncle Steve Agnew on their staff, and they failed with numerous bids in the summer - as they went as high as £14million for him, only for that to be rejected. It is understood the deal being agreed now is somewhat lower than that.
Blackburn have already got cover for Rhodes's departure with Danny Graham arriving from Sunderland earlier this month and a deal being struck for Charlton's Tony Watt on Friday.
HITC Sport understands that Boro finally pulled the trigger on Rhodes after talks with Fulham on Friday.
