I RATE Cyril Rioli only an outside chance to play in Hawthorn's finals campaign with the best-case scenario from his hamstring tendon injury being eight weeks out.
It's his left side that he's injured for the second time this year; the first time it was a standard muscular tear at a low speed and this time it's a higher grade near where the tendon and muscle join.

The club has predicted 8-10 weeks but I think probably 10 is more realistic because it's a recurrence and the way he plays means no risks can be taken.
I don't think we've seen the last of Rioli this year but if he doesn't suffer any setbacks it will be at least the cusp of the finals when he returns.

Sam Mitchell could play this week after eight weeks of rehab from a hamstring tendon injury he sustained in round seven.
The position Mitchell plays and the fact he doesn't rely on speed means he can come straight in.
We saw quite a dramatic incident on the weekend with Heath Shaw where he was struck on the mandible (jaw) by Kurt Tippett's knee.
My immediate thought was a broken jaw or facial bone injury - he went through the traditional concussion posture and fell to the ground unaware.
Shaw was cleared of fractures when he was observed in hospital overnight but it's a high-grade concussion and it's very unlikely he'll play this week with a short turnaround to Saturday's game against Adelaide.
Collingwood has a number of players to talk about this week.
Jamie Elliott will likely miss the trip to the Gold Coast to play the Suns. He'll be frustrated by low-grade hamstring tightness given he's been playing well.
Most players with tightness turn out to have a low-grade strain and the risk of recurrence the following week is high. It's a one-week minimum but more likely a two-week timeout for him.
Nick Maxwell has been training well and I'm expecting him to be in contention to return this week after missing four weeks with a calf, provided he doesn't have any problems this week.
Marley Williams hurt his ankle at training last week and missed the win over Carlton but should return with strapping while Tom Langdon should come back after missing one week with concussion.
Meanwhile, the Pies have said that Ben Reid could play in the VFL this week.
Quads like the one he injured leading into round 13 are usually in the 4-6 week category.
Dayne Beams missed 16 weeks in 2013 with a quad tendon because he kept re-straining it.
Reid will have to be super careful given his history with soft tissue injuries and I think a VFL return this week would be earlier than I expected.
If he does play, it will be limited game time.
For the Suns, Nathan Bock continues to struggle from recurring stress loading pain around the tibia bone and the muscles that were damaged when his leg was broken in 2012.
He's the perfect example of how a fractured tibia can have a permanent effect on a player's career.
There's also Gary Rohan, Matt Maguire, Nathan Brown … we've got a litany of victims.
The outstanding ones are Michael Barlow and Chris Newman, who came back and everyone's forgotten they had broken legs.
But for Bock, there's no easy solution and it's about load management, which means he doesn't train at the level required.
He has played some lower level games but my feeling is he will be permanently plagued by the shin soreness. It's unlikely we'll see him play consecutive games at senior level.
Port Adelaide has picked up a few injuries with Alipate Carlile and Jackson Trengove.
Carlile had a low-grade hamstring late in the game and if we look at the way clubs are treating them plus his age, I think he's probably in the 2-3 week category.
Trengove has an inner medial sprain of the ankle, which takes longer to recover.
The Power hoped he would miss 1-2 weeks but that would be fast for the nature of the ligament injury. His type of sprain – a bit like Dan Hannebery's – is generally in the 3-4 week category at best.
Dan Jackson looks set to return for Richmond after a hip flexor/adductor attachment sprain in his left hip, sustained in round 11.
He has been running freely and played well at VFL level on the weekend so it’s realistic to expect that if he gets through training he'll available.
The Brisbane Lions are optimistic Matthew Leuenberger will train at full capacity this week after playing in the NEAFL following chronic foot, Achilles and ankle problems.
He’s on the cusp of selection but my instinct is he needs more match conditioning – although they’re saying he’s quite likely to come up.
But it's bad news for Brent Staker and Jack Redden.
Staker was coming back from a calf injury and has suffered a mid-foot stress fracture. He would have been pushing the training loads and he'll need a moon boot and also to unload the injury for a period of time.
It's an 8-10 week prediction, which means he won't get back to senior footy this year.
Redden's foot was sore before the weekend and he was subbed out when it worsened. It's a stress related bone problem in his left foot and they're expecting him to miss 6-8 weeks.
As for West Coast's Mitch Brown, I'm still fearful he faces an extended period out after hurting his "good" knee.
He doesn't need an ACL reconstruction but the mechanism of his injury and the bone bruising that occurred is very unpredictable.
The knee – likely to include a low-grade ACL strain - is more of a concern than the ankle he landed on but that could also be a six-week injury.
He doesn't need surgery but bone bruising takes 6-8 weeks to resolve generally and if there's any strain of the ACL, that can be compromised as well.

Essendon's Michael Hibberd is in doubt to face Port Adelaide because of a low-grade hamstring he suffered in the last minute on Friday night while Carlton's Jarrad Waite is battling chronic hip problems and faces restricted training for an indefinite period.
North Melbourne's Jack Ziebell hurt the medial side of his right knee and played the game out with strapping but still has soreness and will have limited training before a fitness test.
The Sydney Swans' Lloyd Perris is apparently set for a "hybrid" knee reconstruction, where the surgeon uses the traditional hamstring tendon and supplements that with some synthetic LARS implant. In theory, this may assist with a speedier recovery.
Anthony Morabito at Fremantle has had a similar procedure.
The Swans are a club that have had the most LARS experience, but it is still a controversial procedure in the medical world due to the unpredictability of future LARS ligament failure.
