Steve McClaren says Marcus Olsson is set for a few weeks out of action with a hamstring injury.

The 28-year-old left-back, who has made 15 appearances so far this season, sustained the injury in the early stages of the 1-0 home win over Birmingham City on Tuesday.After having the injury assessed in the last few days, McClaren has admitted that the defender is set for a few weeks out of action.With fellow left-backs Craig Forsyth (knee) and Max Lowe (groin) sidelined, the versatile Ikechi Anya replaced Olsson against Birmingham and produced a solid display.McClaren told: “Marcus will be out for a few weeks so we’ll have to cope without him.“Max Lowe is also out at the moment with the injury which has forced him to miss the last few weeks.“However, Ikechi Anya came on and did really well against Birmingham. He had a little bit of cramp at the end but that was to be expected after not playing for a while.”McClaren says Anya is set to start at left-back when Derby face Wigan Athletic at home on Saturday.The Scotland international is capable of playing in defence or midfield, on either flank, and has just returned to action from a knee injury.McClaren added: “When Cyrus Christie got injured a few weeks ago he (Anya) was close to going in at right back as well and was the cover there.“Chris Baird has done so well and now Ikechi will have the chance to have a go there (at left-back).”Tweets by @ dcfcofficial
