Port Adelaide duo Dan Houston and Sam Gray are in doubt for Saturday night's clash with Gold Coast at Adelaide Oval.

Houston injured his shoulder in the first quarter of last weekend's 17-point win against the Western Bulldogs in Ballarat, but returned to finish the game.

"I think it's just popped in and out, it was pretty quick," Power midfield manager Michael Voss said.

"He managed to play on, which was good, so he'll be assessed as the week goes.

"With those, they're a bit more about tolerance and we'll make that call later in the week."

Gray suffered a corked thigh after being collected in a marking contest by ruckman Paddy Ryder.

The Power's medical staff will monitor Gray and Houston during the week to decide if they're fit to face the Suns.

Experienced defenders Matthew Broadbent (ankle) and Jasper Pittard (calf) could be available.

Broadbent is likely to get game time in the SANFL to build match fitness after missing the past few weeks, while Pittard could come straight back in if Houston is ruled out.

The Power are likely to recall Jack Hombsch as the replacement for key defender Tom Jonas, who can accept a two-game suspension for his hit on Luke Dahlhaus.
