Wolves defender Jonny has suffered a second serious knee injury in less than 12 months.
The 27-year-old could now be out for the rest of the year after damaging his anterior cruciate ligament in training on Sunday.
He only returned from his first knee injury – suffered last August – in February and had made eight appearances for Wolves this season.
Jonny has also damaged the medial collateral ligament of his right knee – the same knee he injured during last season’s Europa League clash with Olympiacos.
A Wolves statement confirmed: “Jonny has suffered a reinjury to his right knee in training on Sunday. He will need surgery to the MCL and again to the ACL. It is awful news for him. He will see a specialist in London this week.”
Jonny has made 94 appearances for Wolves since joining, initially on loan, from Atletico Madrid in 2018.
Wolves face West Ham in the Premier League on Monday still without Raul Jimenez, who fractured his skull against Arsenal in November.
Nuno fires Jimenez warning
Raul Jimenez will not be allowed to play for Mexico at the Olympics unless he has returned to action for Wolves first, says Nuno Espirito Santo.
Mexico boss Gerardo Martino is eager to take the striker to the delayed Tokyo Games in the summer if he is fit.
Jimenez is still recovering from the fractured skull he suffered against Arsenal in November but is in light training with Wolves.
He linked up with Mexico during the international break as he returns to fitness. But Nuno believes Jimenez needs to play before the end of the season to be in contention for the Olympics.
The Molineux boss said: “I think he must join us, the moment it is clear he can play for Wolves then anything can happen. But, first, he must play for us.
“With all the respect to the national team coach it’s our decision. I understand he is positive and wants to count on Raul for the Olympics but we have to be patient here. We have to make the right decisions, not afford any kind of mistake and respect the doctors.
“He was delighted to be there (on international duty), it made sense. They protected him and he’s a more positive person. All his Mexican team-mates have seen him, asked all the questions but they saw a good Raul and each day he was better.”
