Blackburn Rovers boss Sam Allardyce has played down a pre-season injury concern surrounding Martin Olsson.
The Swedish full-back last just 20 minutes of Tuesday's 3-0 friendly defeat at Preston North End to join a lengthy list of absentees from Allardyce's first-team squad.
Chris Samba, Niko Kalinic and Jason Roberts also missed the defeat at the hands of the Championship side with various knocks.
"We've got a few injuries with Niko Kalinic, Chris Samba and Jason Roberts at the moment, and now Martin Olsson who had to come off with a little bit of tendinitis in the knee," Allardyce told the club's official website.
"So we'll have to keep an eye on those players, we don't think they are too serious.
"We've been feeding back Morten (Gamst Pedersen) as he had been away with Norway for a considerable time and we've been doing the same with Michel Salgado.
"Lars Jacobsen and Vince Grella have just got back with us whilst Brett Emerton and Ryan Nelsen will join us out in Australia.
"So once we get everyone back together in Australia then we'll start forging our way forward in terms of technical and tactical play."
