Newcastle United winger Harvey Barnes is facing four weeks on the sidelines following a hamstring injury picked up against Wolverhampton Wanderers at the start of the month.
Barnes missed Monday night's 3-2 defeat at Chelsea and remains unavailable for Saturday's FA Cup quarter-final at Manchester City (5:30pm kick-off).
"Harvey won't make the squad [v Manchester City] but we hope he'll be back for West Ham," Newcastle head coach Eddie Howe said during his pre-match press conference.
Should Barnes return for the West Ham match, he will have been sidelined for four weeks in total. After being ruled out from September to February with a foot injury, it's a case of more injury frustration for the £38million summer signing from Leicester City.
"[Barnes is] hugely frustrated," Howe said. "He was very, very down after the Wolves game because he knew he just felt something in his hamstring and usually that's going to take a period of time to get right.
"He is desperate to do well for Newcastle. You saw his quality when he came on against Luton and scored instantly.
"He is a goalscorer, we've missed him when he's not been available this year. I know the qualities he has, I'm desperate for him to show that to everybody on a consistent basis.
"Whether this hamstring injury is related to his foot problem, there is a possibility that is the case but we hope he can be back. He's on the grass already so hopefully he'll be back soon and have a positive impact."
1. Matt Targett (achilles)
Targett has been missing since picking up a hamstring injury against Man Utd back in November. He has featured on the bench in their last couple of outings before dropping out v West Ham and Everton in what is understood to be a minor setback in his recovery. Expected return: Tottenham Hotspur (H) - 13/04
2. Kieran Trippier (calf)
Trippier was forced off during the 3-0 win over Wolves with a calf injury. He has since been ruled out for over a month. Set for another couple of weeks out at least. Expected return: Crystal Palace (A) - 24/04
3. Nick Pope (shoulder)
Nick Pope dislocated his shoulder against Manchester United in December and required surgery. Eddie Howe has said the goalkeeper is still a number of weeks away and isn't expected back until 'late April'. Expected return: Sheffield United (H) - 27/04
4. Tino Livramento (ankle)
Livramento picked up a twisted ankle injury at Chelsea which ruled him out for the Manchester City trip. He returned against West Ham United before suffering another ankle injury which will keep him out for another couple of weeks. Expected return: Burnley (A) - 04/05
