Leon Barnett looks set for a lengthy spell on the sidelines as he nurses a knee problem.
The West Brom defender has missed the Baggies' last three games, unable to help the club in their battle against the drop.
While he will be hoping to be back in action before the end of the season, he will be forced to watch on over the course of the next few weeks as his team-mates attempt to secure Premier League survival.
Despite being frustrated at the setback, the former Luton man will be relieved to hear that his injury does not require surgery at present, with West Brom hoping that a prolonged period of rest will see him make a full recovery.
"Leon Barnett has got a knee problem he has had for a long time and which continually flares up," said Baggies boss Tony Mowbray.
"We have decided to take a look at it and he is ultimately going to take a rest for a few weeks and see how it settles down.
"I am not sure if he is out for the season but we have to decide whether he needs to eventually go in and have a look (regarding possible surgery) or whether the knee responds to rest."
Meanwhile, Mowbray has also confirmed that Barnett's fellow centre-half Abdoulaye Meite will miss Saturday's encounter with his former club Bolton with a hamstring injury and illness.
He said: "Meite has got a hamstring problem. It is only a mild one but he is not well on top of that."
