West Coast skipper Darren Glass says he'll probably wait until the tail-end of the AFL season before deciding whether to play on next year.

Glass turns 32 next week but remains at the peak of his powers, highlighted by his fourth All-Australian guernsey last year.

Importantly, the key defender says his body is holding up well and would be able to handle another season at the elite level.

And with West Coast well and truly in premiership mode despite their sluggish start to the year, Glass may find it hard to walk away at season's end.

"I love my teammates. I think this is a particularly good group," Glass said.

"And to be that same group that won the wooden spoon (in 2010) and to be building - it's a nice feeling.

"I just love playing. I love competing. I love the game.

"Physically I feel good. But things change and there's still a long way to go in the year.

"I haven't really thought about (playing on) to be honest, but I would assume perhaps we would talk at the end of the year."

Although Eric Mackenzie has been handed the responsibility of taking on the opposition's best forward for the past few seasons, Glass remains West Coast's most influential defender.

Glass has captained the Eagles since 2008, and will notch his 250th game for the club next week if he can escape injury in Saturday's clash with Brisbane at the Gabba.

West Coast vice-captain Beau Waters is set to miss another match due to an adductor injury while midfielder Luke Shuey will be assessed later in the week after tweaking his calf in Sunday's win over the Bulldogs.
