Wolves have been hit with a major blow with news Matheus Cunha has been ruled out of action with a 'fairly significant' injury.

The Brazilian has enjoyed an excellent season at Molineux after making his move from Atletico Madrid permanent in the summer.

Cunha has scored 11 goals in 28 appearances across all competitions for Wolves, including a hat-trick in their 4-2 win away at Chelsea.

However, the striker played just 20 minutes against Brentford on Saturday before going off injured with a hamstring problem.

It has been claimed for various outlets that the problem will rule Cunha out for the rest of the season, but manager Gary O'Neil has suggested he is working hard to return as soon as possible.

The boss revealed after their 2-0 defeat against Brentford that Cunha said his hamstring 'doesn't feel too bad now', but has since issued a further update on the striker, although has not predicted a return date.

"It’s a fairly significant injury to his hamstring," said O'Neil. "There’s no timeline on it.

"I’ve spoken to Matheus a lot and he just wants to keep pushing to get back as soon as he can. He’s started working on it already, so we’re just going to monitor it week by week, day by day, see how far he can come and how quickly we can get him back.

"He’s keen to get back out there as soon as possible. It’s obviously a big blow to us, to the team and Matheus because of the work he’s been doing – the form he was in was exceptional. These things happen, every team suffers injuries.

"Channy [Hwang Hee-chan] was gone for over a month with the Asian Cup and we managed to keep ploughing on and we need to do the same without Matheus.”
