Arsenal were dealt another injury blow in their title run-in after Kai Havertz hobbled off in the first half of their Premier League clash with Newcastle.
Havertz went down off the ball on 33 minutes, picking up an issue in his upper leg, though the cause was uncertain.

After receiving treatment, the Germany international limped off the field accompanied by an Arsenal physio before heading straight down the tunnel.
Viktor Gyokeres replaced the 26-year-old, who assisted Eberechi Eze’s stunning opener at the Emirates Stadium in the ninth minute.
Havertz was visibly dejected as he made his way off the pitch and down the tunnel, with it uncertain how serious this latest setback could be – or whether it could impact his availability for this summer’s World Cup.
He has been plagued by injuries this season, undergoing surgery on a serious knee injury suffered following the opening day win over Manchester United in August.
That sidelined him for 32 games but he has since had to deal with other injury blows during his journey back to full fitness, including a muscle problem in Feburary.
Arsenal went into the clash with Newcastle joyous over the return of Bukayo Saka from his spell on the treatment table, who started the game on the bench.
But this latest setback will further strain Mikel Arteta’s attacking options as they look to end a six-year wait for silverware under the Spaniard.
