ST KILDA skipper Nick Riewoldt may miss up to two months of football after damaging his medial ligament on Saturday night in a match described by coach Ross Lyon as wreaking "a bit of carnage" on the Saints.

Riewoldt was one of five Saints hurt in the thrilling three-point win over Richmond, Matt Maguire sustaining a foot injury that could sideline him for a number of weeks and Xavier Clarke a hamstring strain that kept him off the ground for much of the last quarter.

Steven Baker was involved in a heavy clash with Brett Deledio in the final term while Sean Dempster was also carrying an undisclosed injury throughout the game.

Lyon said Riewoldt would be out for at least three weeks, although he would not know for sure until scans were done.

"They haven't graded it fully, he's having scans either today or tomorrow and it's going to be anywhere from three to eight (weeks). If it comes out on the good side it will be three weeks," Lyon said on 3AW yesterday.

"That's just an opportunity for (Justin) Koschitzke (and others). We've got a couple of kids ready to go, we've got Jarryd Allen who played in the NAB Cup, a tall forward who was emergency last week. We've got Ben McEvoy, first round draft pick really ready to go at 198 centimetres and 98 kilos.

"Haven't got a full wash on it (Maguire's injury), I was just putting it on the table that it was significant and he will be out for it looks like a number of weeks. Maguire, it's his good foot, so I'm not sure exactly what it is.

"There's a bit of carnage come out of it but (now) it's about attitude and effort from everyone else on the list," Lyon said.

The weekend was a dismal one for this week's Hall of Fame match because Luke Hodge will definitely be out of the clash with a hamstring and Jonathan Brown, Chris Judd, Simon Black and Gary Ablett are in doubt.

Hodge will be out of action for as long as a month after tearing his hamstring on Saturday, the injury happening as the midfielder charged through the centre of the MCG and drove the ball forward on his left foot.

Brown (quad strain), Black (osteitis pubis) and Ablett (calf) were withdrawals from the Geelong-Brisbane Lions clash on Saturday.

Chance Bateman was another casualty for the Hawks, sustaining a broken hand.
