The FA have until 5pm today to formally appeal against the ban the Manchester United striker incurred for his dismissal in last month's qualifying match against Montenegro.
The victim of Rooney's challenge, defender Miodrag Dzudovic, has written to Uefa to lend his support to the striker.
However, Rooney insists there is no-one to blame but himself.
The 26 year-old said: "Obviously, it's devastating for me but it's something that's my own fault, so I can't really complain.
"It was stupid by me - I regretted it as soon as I did it. It's no excuse, but I still feel the punishment is a bit harsh. I'm disappointed with it.
