West Bromwich Albion's Swedish defender Jonas Olsson is set to be sidelined for more than a month by an Achilles injury.
The versatile 27-year-old has not featured since being replaced in the 2-1 win at home to Fulham two weeks ago and is now facing an extended stint on the sidelines.
Manager Roberto Di Matteo told the club's official website:"With Jonas we're looking at a longer injury rather than a few weeks.
"I'd like to hope it will be weeks rather than months for him. It's going to be around the five or six-week mark.
"It's an injury where he can improve dramatically, but he's not going to be back within two weeks – that's for sure."
Olsson joined the Baggies in the summer of 2008 from Dutch side NEC Nijmegen and has since scored nine goals in 85 appearances in all competitions.
