BRISBANE Lions coach Michael Voss has called for a lift from full-forward Brendan Fevola as his side tries to arrest a horror form slump.

The Lions have alternated four-game winning and losing streaks to begin the 2010 season, and Voss said Fevola, who managed just one goal from three disposals in Saturday's night's 81-point loss to Geelong, is paying the price for a lack of time on the training track.

“His work rate is not high enough, and as a result you always look a little bit sorer and don’t look like you’re as into the game. That’s something he has got to address quite urgently," Voss said.

“He’s had a couple of little ailments that have prevented him from training."

Voss is confident that his side can return to winning ways when it comes up against Adelaide at AAMI Stadium this Sunday.

“We’ve had a couple of great training weeks, (and) sometimes there is always a little bit of lag behind that,” Voss said.

“As strange as it might seem, I actually thought that we made some ground in some certain areas (against Geelong).

“When you look across the board, in a lot of statistics we were quite measurable against them during some of the quarters ... ultimately in their forward half they were just cleaner than us.”

The Lions had more inside 50s than Geelong in the first half (31 to 29) and more tackles for the game (63 to 45), but it was all one way traffic on the scoreboard.

Voss admitted his players had lost some confidence, and needed to use Saturday night’s loss as motivation.

“My biggest motivators have not come from my greatest wins but my greatest losses,” Voss said.

“We’ve got to be motivated by that (losing) and be determined to be able to turn it around.

“Part of that starts by what we do on the training track, and (with) our approach to that and the last couple of weeks, I would say that we’ve started to turn that corner.”

The Lions have more bad news on the injury front, with defender Ash McGrath having scans on Monday for a hyper-extended elbow.

Full-back Daniel Merrett is out for another two to three weeks after re-injuring his hamstring at training, while Mitch Clark is struggling to overcome a groin complaint and is unlikely to come up for Sunday’s clash with the Crows.

The Lions have an eight-day break before facing the Crows, who have plunged to second-last on the AFL ladder. Voss said the extended break is a good opportunity for his side to regroup, both physically and mentally.

“The eight days is really when you want to make your most gain,” Voss said

“It’s about being able to make sure that we recover and get ourselves 100 per cent right. We’ll get a fair bit more training done this week, which is nice.

“It’s an important game for both sides to get their seasons on track.”
