Genia did a fine job and led the Reds into fifth place in the 2010 Investec Super 14, the Queenslanders' best finish since 2002. They also broke the record for the most points in a season and defensively the Reds conceded less than ever before in the Super 14.
And despite Horwill's return to fitness, Genia has expressed his desire to hang onto the role.
"I was proud to captain Queensland last year and if I'm not captain I'll be a bit disappointed," said Genia.
"The big thing is, though, everyone has to lead in their own way. We all have to put our hands up."
Reds coach Ewen McKenzie has already admitted appointing a captain will not be an easy decision to make and pointed to Wallabies prop Ben Daley as another worthy candidate.
"We've got more options this year than we did last year," said McKenzie.
"You want to identify leaders by name but you also hope there will be a bunch of players who lead by example, by enthusiasm and by experience.
"It was tragic what happened to James last year but it gave Will an opportunity and he stepped up. That's how it works."
Since making his Australian debut in 2009, 22-year-old Genia has gone on to establish himself as one of the game's leading number nines. The 20-cap Wallaby is just one of an exciting group of youngsters in Australia's set-up that will lead their charge against the Lions in 2013.
