Hawthorn have confirmed both Cyril Rioli and Paul Puopolo will miss at least the next month of football after sustaining injuries during the Hawks' win over Melbourne on Sunday.

Rioli got a knock to the knee during the second quarter, while Puopolo suffered a hamstring injury during the third term.

โ€œWe had a really challenging day on the injury front,โ€ Hawthorn's Director of High Performance Andrew Russell told hawthornfc.com.au.

โ€œCyril has a moderate grade medial injury.

โ€œIt is on the same side as his PCL last yearโ€ฆ but itโ€™s not related at all.

โ€œIt looks like itโ€™s probably in the five to six week range at this stage. 

Puopolo's injury wasn't as bad as first thought, although he'll still miss a fair chuck of time.

โ€œHeโ€™s probably pulled up a fraction better than we thought he would have,โ€ Russell added. 

โ€œHeโ€™s got a decent hamstring strain and heโ€™s going to miss four to six weeks.โ€

Hawthorn veteran Shaun Burgoyne will be unavailable this weekend, although he could return from his hamstring injury as early as round six.
