There is positive and negative news on the injury front for Melbourne this week as it prepares to battle Fremantle, while three Bulldogs face fitness tests ahead of their clash with Geelong this Saturday.

For the Demons, key forward Ben Brown will miss a second consecutive game, while defender Jake Lever is set to return and midfielder James Jordon is expected to play.

Brown missed Melbourne's loss to the Western Bulldogs last week due to knee soreness, while Jordon played out the Dogs game after overcoming a knee complaint.

Lever suffered a shoulder injury during the club's Round 18 win against Port Adelaide and is pushing to return for the Dees' all-important meeting with Fremantle this Friday night in Perth.

Meanwhile, Bulldogs midfielder Adam Treloar and defenders Caleb Daniel and Taylor Duryea face fitness tests ahead of the club's clash with Geelong this Saturday evening.

Bulldogs sports medicine guru Chris Bell stated Daniel and Duryea have reached the final stages of their respective rehabs and could put their hands up to play this weekend.

"Caleb and Taylor have recovered really well following their knee injuries," Bell told westernbulldogs.com.au.

"Both are in the final stages of their rehab and have both worked extremely hard to get back to full capacity.

"Both will come back into full training this week and if they tick our final boxes, both will put their hand up for selection."

As for Treloar, the prolific ball-getter was subbed out in the later stages of the Dogs' win last week as a precaution, with his availability this weekend uncertain.

"Adam came from the ground in the fourth quarter with low-level calf tightness," Bell continued.

"We didn't want to take any risks with Adam, so we substituted him out of the game.

"We will work through a process with Adam this week to determine his availability."

The Bulldogs will look to retain their place in the top eight when they face the high-flying Cats at GMHBA Stadium.
