Gestede, who netted a double against The Tigers in the 3-1 victory, picked the injury up in the final minutes of the victory at the Riverside.

It’s another blow for Gestede, who missed several months earlier in the campaign due to a 'freak' training ground injury which subsequently required multiple surgeries.

Boro manager Tony Pulis said: “He won’t play again this season, we don’t think.

"It’s a massive blow for us as a football club. Out of all of the strikers, he’s looked the most likely to score in the games we’ve played.

"We’re really disappointed, but we’ve got options up there, whether it’s Patrick [Bamford] or Britt [Assombalonga], they have to step up to the plate."
