Hull are interested in Boro striker Ashley Fletcher, manager Nigel Adkins has confirmed.
The forward has featured six times in the Championship this season but has largely been limited to cameo appearances.
The league cup has heralded more success for the former Manchester United youngster, having scored three times in five games before Boro’s exit to Burton in the quarter-finals.
Hull held a strong interest in Fletcher in the summer, and were even close to finalising a deal.
But Tony Pulis pulled the plug after uncertainly over Martin Braithwaite’s future.
“Ashley is a player who we actually had down at Cottingham in the summer,” Adkins said. “It didn’t happen, Middlesbrough pulled the deal at the very last second, which was a shame.
“He’s one of many talented footballers that we’ve tracked. We have spoken with Middlesbrough about Ashley and you never know.
“As it stands at the moment, it’s not happening. But that’s not to say it might not happen, if that makes sense.”
Fletcher is likely to be one of many departures this month, with Boro needing to trim a hefty wage bill.
Paul Lambert’s side are also keen on striker Rudy Gestede, although wages appear to be a stumbling block in any potential deal.
