Olsson (achilles) is expected to miss this Saturday's game against Crystal Palace, manager Alan Irvine told the Express & Star.

Olsson (achilles) has been troubled by the problem for a number of years and the latest flare up could mean time for surgery. “It's been something that has been bothering him for some considerable time," manager Alan Irvine said. “He has had an injection, and if you can imagine getting an injection in your Achilles, it's not nice. He's in a bit of discomfort still." Olsson has been displaced from the side by the central defensive duo of Joleon Lescott and Craig Dawson and would only make the bench if he was fit.

Olsson is suffering from an Achilles injury and he has not been able to participate in training this week, making him a serious doubt for Monday's match at Manchester City, the Birmingham Mail reports.

Like most defenders, Olsson's fantasy value is primarily derived from clean sheets, something he's managed to do just twice in 2014.

Olsson picked up a yellow card in Saturday's win at Swansea, his 10th of the season. He will now miss the next two matches and be available again on April 5 against Norwich City.

Olsson will miss a match at Hull City and then a home game against Cardiff City, two solid opportunities for clean sheets. Outside of that, he is not much of a fantasy producer.

Olsson suffered an injury during Sunday's match against Liverpool and had to be replaced by Diego Lugano.

The full extent of the injury will likely be announced after the game, although it was obviously serious enough that he had to come off immediately after suffering the knock.

Olsson scored in the 38th minute of West Brom's 1-1 draw with Tottenham on Thursday.

Olsson's goal came just two minutes after Christian Eriksen started the scoring during Thursday's match. Olsson's effort was his first score in March 2012, as the defender primarily relies on clean sheets to produce fantasy value.

Olsson signed a new four-year contract with West Brom, reports the Premier League.
