Scans have revealed Hawthorn key defender Ben Stratton has suffered a low grade hamstring strain.

"Unfortunately today the scans confirmed Ben has suffered a low-grade hamstring strain,” Hawthorn's Director of High Performance Andrew Russell told the club website.

“Ben won’t take part in our match next week and will be a test beyond that, depending on how our finals campaign progresses.”

The three-time premiership player left the ground half way through the third quarter of Hawthorns loss to last year's premiers Richmond on Thursday night at the MCG.

Stratton has been Hawthorn's most reliable defender and hasn't missed a game this season.
