That’s according to a report from Football League World, who suggest that the 25-year-old could find himself erased from Neil Warnock’s plans entirely on Teesside.
Wing enjoyed a successful campaign for Boro last term, scoring seven goals in 40 Championship outings, but drifted out of the starting XI in the early stages of this season, and ultimately had to move to Rotherham United on loan to seek first team opportunities in January.
Since then he has made nine Championship appearances for the Millers, including eight starts, registering one assist in the process.
Back on Teesside, however, Wing has slipped behind the likes of Sam Morsy, Jonny Howson, Paddy McNair, and George Saville in the pecking order, and it is claimed that a number of Championship clubs would be keen on snapping him up if Boro decide to sell this summer.
Whether current side Rotherham are among those vying for his signature remains to be seen.
Elsewhere, it has been reported that long-term Boro target Kamil Grosicki could be on his way out of West Brom this summer.
The Polish international has been starved of opportunities at The Hawthorns this season, making just three Premier League appearances all term.
With that in mind, the Birmingham Mail claim that he is headed toward to the exit door, in the coming months.
As recently as January, the Sun were reporting that Boro and Nottingham Forest were keen on the winger, who has 80 caps for his country.
