ST KILDA forward Fraser Gehrig could come under scrutiny from the AFL match review panel following a crude hit on Western Bulldogs defender Brian Harris last night.

The Saints bounced back from last week's loss with a convincing 50-point win over the Bulldogs at Telstra Dome but Gehrig, who finished with one goal from his 12 touches, could be in doubt for the Saints fourth round clash with Essendon.

Coach Ross Lyon said he missed the incident about eight minutes into the third term, just moments after Gehrig had a shot at goal but missed.

"I didn't see anything, I was watching another part of the ground (but) I have faith in the system," Lyon said.

Apart from the Gehrig incident the Saints came out of the match without any injury concerns, co-captains Nick Riewoldt making a successful return from a hamstring injury with four goals and Lenny Hayes continuing to build his confidence after 10 months out of the game following a knee reconstruction.

Lyon was pleased with the form of his leaders as well as the game of Clinton Jones, who booted a late goal and picked up 14 touches on debut.

"We we're keen to come away with the four points and it takes a bit pressure off," he said.

"It's nice to be 2-1 but there's no respite, we start reviewing and preparing for next week, there's no easy ones."

He praised the efforts of veteran Robert Harvey, who finished with 24 touches and seven marks, saying he was "one of the games great runners" who influences games even without the ball.

"He's one of the game's great runners isn't he, you talk about Judds and Kerrs and Lappins and Bradleys, but he's up there with them," Lyon said.

"It's what he does, he chases, tackles and sets the tone.

"There were some really good signs for Lenny too, to miss 10 months it's very hard to come back and pick up where you left off and I thought the longer it went, the better he looked."

Lyon was also happy with the way Riewoldt slotted in alongside Gehrig and Koschitzke.

"The three of them are very talented clearly, you come in and you can't tighten the reins on them too much, you've got to say basically work together," he said.

"John Barker, our forward coach, he's done a pretty good job working with them, but there's no substitute for talent."

After their second loss in a row Bulldogs coach Rodney Eade was disappointed and attributed the loss, partly, to a drop in confidence.

"There's no doubt, but we've come up against two pretty good sides," he said.

"The good thing about this game (is) you get back on the bike pretty quickly.

"We'll have a review and address a few things but what happened in round one (compared) to the next two rounds, I don't think you'd see that coming."

He said when his side was forced into making errors by the Saints last night, and by Adelaide last week, his side started playing conservatively.
