"Whether Robbie stays in the game or steps away for a break he has our full backing."
While not a huge star, openly gay footballers are still very rare, and Rogers is the biggest to have come out in a long while.
The California-born player made his name in Major League Soccer with Columbus Crew and was part of the USA team at the 2008 Beijing Olympics.
Rogers, capped 18 times by his country, recently played for Championship side Leeds United before his release from Elland Road last month and also had a brief a loan spell at Stevenage.
Only two other footballers have publicly said they are gay, despite a number of high-profile male and female homosexual athletes from other sports openly discussing their sexuality in recent years.
In 1990, former England U-21 international Justin Fashanu was the first professional footballer in Britain to reveal he was gay. He took his own life eight years later, aged 37.
Swedish lower league player Anton Hysén publicly announced his homosexuality in an interview with a football magazine in 2011.
