Geelong have confirmed skipper Patrick Dangerfield will spend a short spell on the sidelines after suffering a hamstring injury in Saturday's win over Adelaide.

Dangerfield was subbed out of the match in the second half due to a hamstring concern, with scans revealing a low-grade strain for the veteran midfielder.

The injury blow comes amid a strong period of form for the 33-year-old, who has been a key figure in Geelong's undefeated five-game run.

"Pat has been in fantastic form, so we are disappointed to lose him for the next few weeks," Cats football boss Simon Lloyd said in a club injury update.

"It's positive news that it's on the lower end of a hamstring injury, Pat has already commenced his rehabilitation program and will continue his strong leadership across our football program."

The Cats are scheduled to face Richmond, Fremantle, GWS and the Western Bulldogs across their next month before their fixtures mid-season bye in Round 13.

Geelong is already without a contingent of their premiership-inning side from last year's grand final, with Cameron Guthrie (toe), Jack Henry (foot), Rhys Stanley (eye), Tyson Stengle (arm) and Zach Tuohy (back) all currently out of action.

The Cats are set to lose forward Brad Close for Friday's clash with Richmond, unless the club is successful in its challenge of the one-game suspension for rough conduct.

Geelong and Richmond will meet at the MCG on Friday night at 7:20pm (AEST).
