Interesting, just found it on the NRL site
The Roosters will play their home games from the SCG, with matches from round 11 listed with venue "TBA" while the NRL awaits the release of the AFL draw and the Sydney Swans' requirements but it is not expected to result in any changes to the NRL schedule.
It will be interesting to see how this pans out, there are going to have to be some weekends when both teams play at the SCG, the Swans games at the SCG for the last couple of years have been top heavy with Saturday night games and also quite a few Friday night and a couple of Thursday nights, they don't play many Sunday games there and I noticed 4 of the Roosters games are down for Sundays, time will tell when the AFL draw is out.
