Newcastle United were dealt a fresh injury concern during Saturday's 2-2 Premier League draw with AFC Bournemouth at St James' Park.
Fabian Schar left the pitch with his arm in a makeshift sling at full-time after the ball hit awkwardly off him during the closing stages of the match. The defender left St James' Park with his right arm strapped up.
Eddie Howe will be hoping to have Schar back available for the trip to Arsenal on Saturday (8pm kick-off) as The Magpies look to extend their chaotic unbeaten run to five matches in the Premier League.
Newcastle will also be hoping for fitness boosts in the form of Alexander Isak and former Arsenal midfielder Joe Willock, who are both understood to be 'very close' to returning to action following respective groin and Achilles issues.
But the likes of Elliot Anderson and Matt Targett are unlikely to be back in contention for the weekend while there are longer-term issues with Nick Pope, Callum Wilson and Joelinton.
As things stand, Newcastle have nine players either doubtful or ruled out of the trip to the Emirates Stadium, a ground they have not won at since 2010. But Newcastle can take some encouragement from becoming the first side to beat Arsenal in the Premier League this season when they last met at St James' Park in November.
Anthony Gordon controversially scored the only goal of the game to help The Magpies claim all three points.
1. Anthony Gordon - knee
Limped off against Chelsea with a knee issue. Eddie Howe admitted it didn't look 'too good' afterwards. Expected return: TBC (April-May 2024)
2. Dan Burn - knock
Was taken off at Chelsea after falling on his back. Eddie Howe played down any injury concerns after the game. Expected return: Manchester City (A) - 16/03
3. Harvey Barnes - hamstring
Missed Chelsea with a minor hamstring issue. Is a major doubt for the Manchester City match. Expected return: West Ham United (H) - 30/03
4. Kieran Trippier (calf)
Trippier was forced off during the 3-0 win over Wolves on Saturday with a calf injury. Following a scan result, Trippier has been ruled out for a few weeks. Expected return: West Ham (H) - 30/03
