AARON Hall is likely out for the season after confirmation of a pectoral injury suffered in Saturday's loss to Geelong.

The Gold Coast midfielder had scans on Monday night, and the results showed he would miss 10-12 weeks.

Based on that, the best-case scenario is Hall could be back for the final two or three rounds of the season.

"We’re seeking a few specialists' opinions over the next couple of days and we'll know better for his plan moving forward after we've chatted to those," Gold Coast rehabilitation manager Alex Rigby told the club's website.

Hall is out of contract, and told AFL.com.au last week he had "not sat down and thought about it" when asked about his future. 

Hall's injury news comes on the back of co-captain Steven May's ankle injury that will sideline him for four to six weeks.

In further bad news for the Suns, running defender Kade Kolodjashnij was a late withdrawal in the NEAFL with concussion symptoms and has no immediate return date set.

"He'll be out for an indefinite period of time at the moment whilst we seek a few specialists' opinions, and following that we'll come up with a management plan and hopefully see him back out on the training park pretty soon," Rigby said.

Kolodjashnij has battled with concussion over the past two seasons.
