Winnall has impressed since joining Derby County from Sheffield Wednesday in August.
Caretaker manager Lee Bullen says Sheffield Wednesday will definitely look into recalling Sam Winnall from Derby County.
However, the Scot is unclear as to whether or not it will be possible to bring the 26-year-old back to Hillsborough.
Winnall has scored six goals in 13 games since joining Derby on loan in August – a deal which saw Rams midfielder Jacob Butterfield move in the opposite direction.
Asked if Wednesday can get him back, Bullen told BBC Radio Sheffield: “I’m not sure exactly what the agreement is with Derby. I’m not sure if both clubs have to agree.
“I know Derby had an issue when [Chris] Martin was down at Fulham last year – I don’t know if it’s a similar scenario.
“It’s one thing we’ll definitely have to look at. But again, I don’t know what the actual agreement was, that was done way before my time, so we’ll have to look at that – as a potential.”
While Derby have soared to second in the Championship with Winnall on board, Sheffield Wednesday have struggled in his absence, with Monday’s 3-0 defeat to Burton Albion leaving them in 16th place – six points above the relegation places.
Former Aston Villa and Wolverhampton Wanderers manager Paul Lambert is the heavy favourite to succeed Carlos Carvalhal at Hillsborough.
The Owls hired Katrien Meire as chief executive on Monday, days after the unpopular Belgian left the same role at Charlton Athletic.
