Tough defender Beau Waters is seen as Glass's natural successor after he was appointed the sole vice-captain two years ago.
However, Glass is likely to hold on to the captaincy for at least one more season as Waters' durability and readiness for the 2013 is being tested after another injury setback last month.
Waters needed hip surgery before Christmas and is unlikely to be ready for the new season.
Glass took over from Chris Judd as captain and has led the side for the past five seasons.
Glass was named All Australian captain in 2012 as the skipper is still a strong contributor.
Glass is entering his 14th AFL season and the 31-year-old said he is ready to hand over the reins to a younger teammate, likely Waters, before his career ends.
"I'm happy with whatever the club decides," Glass said on Wednesday.
"If they want me to continue I'm happy to do that, and if the timing is right for someone else, I'm happy with that as well."
After the 2012 season Eagles coach John Worsfold said Glass could still play a significant leadership role at the club, even without the title off captain.
"He's an outstanding leader and outstanding captain," Worsfold said.
"If he wasn't actually named captain, it wouldn't mean that his leadership would drop away.
"He would still offer fantastic leadership around our club and possibly in an even stronger role supporting a developing captain."
Although Waters looks to be the Eagles' likely next captain, 22-year-old club champion Scott Selwood is highly rated and could take over as vice-captain.
Eagles players vote on who they would like to captain the club, then the final selection is decided by Worsfold and the club board.
