The striker conceded earlier this evening that he could be prepared to leave the Whites following the sacking of manager Brian McDermott, which still has not been confirmed by the Championship outfit.
However, having taken to Twitter, McCormack revealed that he is planning to be a part of the team that takes on Huddersfield Town at Elland Road tomorrow afternoon.
"Lets all be united tomorrow. An unreal atmosphere and 3 points and move this great club forward. See yous tomorrow," wrote the 27-year-old.
The likes of Cardiff City and West Ham United were said to be interested in McCormack.
