Milan: Veteran Lazio striker Miroslav Klose is expected to be sidelined for several weeks after being diagnosed with a left thigh muscle injury, according to the Serie A club's doctor.

Klose hobbled off at half-time during Lazio's 1-0 win over Bayer Leverkusen on Tuesday in the first leg of their Champions League play-off. Replacement Keita Balde scored the winning goal for the Biancocelesti in midweek, but they could now be without the 37-year-old German Klose for up to four games, according to Stefano Salvatori.
