Liverpool manager Brendan Rodgers has delivered mixed injury news ahead of the Reds' visit to the Hawthorns on 25 April.
Daniel Sturridge has been ruled out indefinitely by the manager as the striker is yet to recover from a hip injury he sustained during their FA Cup quarter final victory over Blackburn Rovers. Rodgers is unaware as to the time needed for the striker to return.
The England international forward has had an injury ravaged season, which saw him miss five months of action before returning in February and has since had a start-stop return with small niggles affecting his progress.
This will be a big blow for the manager, as he will have to continue deploying Raheem Sterling in a central role due to Mario Balotelli and Rickie Lambert's lack of form in front of goal.
After entering 2015 in blistering form, the Liverpool campaign is in the midst of a collapse as the last few weeks have seen them lose games to Manchester United and Arsenal as well as getting knocked out of the FA Cup by Aston Villa.
The Northern Irishman will be keen to finish the season on a high and will hope that all his players return for the end-of-season run in.
On the other hand, Adam Lallana has returned to training after recovering from a groin injury he picked up during their loss to United at Anfield. The manager confirmed that he could be available for the clash against West Bromwich Albion on Saturday.
"Lallana has just come back into training the past few days so we will see how he is for the weekend but none of the others (who have been injured) will be fit," Rodgers said, as quoted by the Liverpool Echo.
"We're unsure at this moment how long Daniel will be out. He certainly won't be available for the weekend," the Reds manager added.
"Jon Flanagan is now training with the team but he's a way off fitness. We just need to monitor his rehabilitation," Rodgers explained.
Meanwhile, Lallana has revealed that he did suffer a setback in his recovery process, but has now declared himself fit ahead of Saturday's clash.
The midfielder admitted frustration at being sidelined for the second time this season with a groin injury, but believes he is on top of it now and is gearing up for the end-of-season run-in with the focus on carrying the momentum into the next season.
"I had a groin issue. I've had a couple of them this season, but I'm back on top of it now, which is good," Lallana told Liverpool's official site.
"I'm back fit now, 100 per cent and have trained the last two days. It was frustrating as I had a bit of a recurrence of it before the Arsenal game, maybe due to being a little bit too eager to get back."
"But I've trained well, I feel good and I'm ready for the run-in. I'm looking forward to pushing on now, pushing on [next season] and improving on this season," the England international midfielder added.
