Takehiro Tomiyasu will miss the remainder of Arsenal's push for the Premier League title due to a knee injury.
The Japan international was withdrawn in the opening exchanges of the Gunners' Europa League clash with Sporting CP last week, with Mikel Arteta's side losing that game on penalties following a 1-1 draw at Emirates Stadium.
Following Arsenal's 4-1 victory over Crystal Palace on Sunday, Arteta conceded the situation was "not looking good" for the defender.
It has now been confirmed that Tomiyasu will be out for the rest of the campaign after the 24-year-old underwent surgery.
A statement from the club read: "Following his substitution during last Thursday's Europa League match, subsequent assessments have confirmed that Takehiro Tomiyasu sustained a significant injury to his right knee.
"Tomi has had successful surgery in London on Tuesday and will be ruled out for the remainder of the season.
"Everyone at the club will now be working hard with Tomi, so he can join pre-season training ahead of next season."
Tomiyasu featured in 21 matches across all competitions this season for Arsenal, who are hunting their first Premier League title since the 2003-04 season, though just six were as a starter, with Ben White establishing himself as first-choice on the right side.
The Gunners hold an eight-point lead over Manchester City, who have a game in hand, with 10 matches to play.
Rennes make top four, Nantes survive and Auxerre relegated on Ligue 1 final day
Rennes edged out Lille and Monaco to secure a top-four finish while Nantes' first league win since February saw them stay up at Auxerre's expense on a dramatic final day of Ligue 1 action.
Rennes clinched a 2-1 victory against Brest thanks to a Benjamin Bourigeaud brace, seizing on Lille's 1-1 draw with relegated Troyes and Monaco's 2-1 reverse against Toulouse to take fourth.
Bruno Genesio's side thus secured Europa League football for next season, while Paulo Fonseca's Lille must settle for a Europa Conference League spot and Monaco missed out entirely.
Champions Paris Saint-Germain squandered a two-goal lead in a 3-2 loss to Clermont, meaning they finished just one point clear of runners-up Lens, who ended the season with a 3-1 win at Auxerre.
That victory allowed Nantes to finalise a great escape in their final game, vaulting Auxerre to secure safety with a 1-0 win over relegated Angers.
Nantes therefore secured top-flight football for another year, evading the expanded four-team relegation zone by a single point ahead of the division being cut to 18 teams.
Auxerre, Ajaccio, Troyes and Angers will play in Ligue 2 next season, with Le Havre and either Metz or Bordeaux coming up from the second tier.

Paris Saint-Germain 2-3 Clermont: Messi and Ramos denied winning send-off as visitors fight back
Paris Saint-Germain failed to muster a winning send-off for Lionel Messi and Sergio Ramos as they ended the Ligue 1 season by squandering a two-goal lead in a 3-2 loss against Clermont.
Early goals for the Spaniard and Kylian Mbappe put the champions on top at Parc des Princes, before Johan Gastien, Mehdi Zeffane and Grejohn Kyei completed a stirring comeback from the visitors.
It was a damp last note for ex-LaLiga heroes Messi and Ramos, who leave Paris as two-time league champions but without having won supporters' hearts – with Messi booed ahead of kick-off.
Likewise, it may prove a dour final chapter for coach Christophe Galtier, who is widely tipped to depart despite leading PSG to a record 11th league title.
PSG, who wore shirts adorned with the name of injured team-mate Sergio Rico in the first half, needed VAR to rescue them after Kyei prodded home an early finish.
The hosts promptly seized control, with Ramos netting a farewell header from Vitinha's delivery before Mbappe doubled their lead with an excellent penalty following Alidu Seidu's foul on Achraf Hakimi.
Clermont refused to fold though, with Gastien capitalising on Marco Verratti's mistake to halve the arrears and Zeffane bundling in a leveller either side of Kyei putting a spot-kick wide in a thrilling first half.
Messi, who misfired on his farewell, spurned a chance to finish Mbappe's square ball after the restart before Kyei nosed the visitors in front with a close-range finish.
PSG continued to toil for an equaliser in the closing stages and Messi almost stole a point in the final minute of injury time, only for goalkeeper Mory Diaw to stop his direct free-kick with an acrobatic save.
