The leagues should he delayed for at least two weeks to due this terrible tragedy. I think everyone should help out and this is were players and club influence must kick in so that all the people that were hurt get the care they need. Health first then football comes later.
It will probably be delayed. Hatay and Malatya decided to withdraw from the league. Right now it's so insignificant, it's people and their lives that matter.
Seems like there won't be any type of withdrawal from the league, teams will keep on playing "eventually". Two things will happen for sure, which happened in other nations and I do not know why Turkey wouldn't be same, so my guess and previous disasters in other nations show; the teams that this happened will play in other cities, and other cities will not only provide free stadium for these teams, but they will provide free training grounds and hotels or houses to stay as well, since these are rich players, it won't be issue for players anyway but the workers will be in either hotels or cheap housing.
Secondly, it will not be postponed for a few weeks but until there is no more thing to do. Right now they are still digging, we are talking about over a month of work left, all those rubbles being cleaned up will take more than a month, maybe more. I wouldn't be shocked to learn if league is cancelled for the whole year, but if not, we should expect earliest April for restart, or late march at least.
