JOSH Kennedy is a chance to play against Port Adelaide but he will have to wait another day or two before knowing if he has avoided a long-term problem with his right elbow.

Kennedy had scans on his injured elbow on Monday and he was expected to know by Tuesday afternoon the full extent of the damage and whether he would be available for Sunday's clash with Port Adelaide.

But Eagles general manager of football Craig Vozzo said the club was still assessing the injury and would need another day or two to determine whether Kennedy requires any long-term rehabilitation.

"It's a complex injury," Vozzo told the club's website.

"So we're going through the assessment phase at the moment. We're still hopeful that we may have avoided a long-term problem but we'll know in the next day or so exactly where that's heading and we certainly haven't ruled him out for the weekend."  

Matt Rosa (back-related hamstring) and Xavier Ellis (hamstring/calf) will both undergo fitness tests later this week.

Rosa has only missed one match after pulling up sore from the trip to Brisbane in round four but Ellis will likely have to return via the WAFL as he has not played since the pre-season.

Midfielder Scott Selwood is on track to return from his ankle problem in a couple of weeks.

Vozzo said key forward Jack Darling was making positive inroads after a couple of sessions with the main group.

However, Darling will need up to a month of training before being available to play, having missed the entire pre-season with a stress fracture in his foot.
