Barcelona midfielder Marc Casad is likely to miss the rest of the season after injuring his right knee during Sunday's 4-2 victory over Atltico Madrid, sources have told ESPN.
Casad picked up the injury during the first half at the Metropolitano, but played on until midway through the second period, when he was replaced by Eric Garca.
Bara said in a short statement he will undergo further tests in the coming days to determine the severity of the problem and the treatment required moving forward.
The 21-year-old was enjoying a breakout season under Hansi Flick after being formally promoted to the first team last summer.
He has featured 35 times across all competitions, with his performances with his club earning him a Spain debut last November.
Spain coach Luis de la Fuente had also called him up for this week's UEFA Nations League quarterfinal against the Netherlands, but he has been forced to drop out, with Bayer Leverkusen's Aleix Garca taking his place.
Bara defender Iigo Martnez has also pulled out of international duty with Spain this week. Bournemouth's Dean Huijsen has been promoted from the under-21 side to replace him.
"Tests have confirmed that Martnez has lateral meniscus inflammation in his right knee," Bara said. "He will be treated in Barcelona under the supervision of the club's medical staff."
ESPN Sources don't expect Martnez, who has formed a partnership with Pau Cubars in the middle of Bara's defence this season, to be sidelined for a significant amount of time.
Casad's absence, meanwhile, denies Flick of a key rotation option in the middle of the pitch, although he still has Frenkie de Jong, Pedri, Gavi, Fermn Lpez and Dani Olmo available, while Garca has also been used as a defensive midfielder, too.
The only other Bara players sidelined for a significant period are Marc-Andr ter Stegen and Marc Bernal, with defender Andreas Christensen expected to return to training soon.
