Twitter has a lot of big dreams for former Australian NFL player Jarryd Hayne

Well, that was brief.

Jarryd Hayne, the Australian rugby league player who captured our imagination and converted to American football, announced his shock retirement from the NFL on Monday after only one season.

The ex-San Francisco 49er will attempt to chase another dream by trying to make the Fiji rugby sevens team for the 2016 Olympics in Rio De Janeiro, only nine months after his debut in 2015's NFL pre-season.

It turns out Hayne might have to keep himself occupied with another pursuit, as he could be ruled out due to strict rules by anti-doping agency WADA, requiring him to sit out for six months before he can play another professional sport, according to Fox Sports. The 2016 Olympics begin in August.

Luckily, Twitter has come up with some alternative dreams for Hayne to pursue if the Olympics thing doesn't quite work out.

Whatever Hayne's next boyhood dream may be, it'll be fun while it lasts.
