The Western Bulldogs expect to regain No.1 ruckman Tim English for Friday night's big clash with Sydney at the SCG.

Coach Luke Beveridge is also confident star onballer Adam Treloar will play after he pulled up with hamstring tightness in last week's loss to Brisbane.

"He should be fine ... he'll train today and gear up for the game," Beveridge said of Treloar.

English has missed the last two games because of delayed concussion symptoms.

Defender Ed Richards is another player set to return after a game out because of concussion.

"It's a big session today for us and they'll get through, they'll be available," Beveridge said before Tuesday morning's session at Whitten Oval.

The 41-point loss to the Lions left last year's grand finalists a game outside the top eight amid a challenging run of matches against the Swans, St Kilda, Melbourne, Geelong and Fremantle - all above the Dogs on the ladder.

But Beveridge remains upbeat, saying after the Brisbane game "I won't stop believing."

He noted on Tuesday that there are plenty of games left and the Bulldogs remain in charge of their destiny.

"Nothing's missing - there's a third of the season, or just under, still to go and you've got to remember that," Beveridge said.

"Our form line has been relatively strong in recent times, we've just been beaten by a good side.

"The alarm bells aren't ringing."
