In fantasy football, how long do you have to reject or accept a trade offer?

Question

For example, if you offered a trade to someone, could they wait until the preseason games are over to decide?

They get the edge here because if someone gets injured, then they can go ahead and accept the trade, and you would get damaged goods.

Is there a way around this?

Answer 1

In my league the guy who can accept or decline has 3 days to respond.

There is no way around this in most leagues you have 3 days to answer.

Answer 2

It depends what league your in, in espn you can set a limit but on nfl.com it is unlimited, but if you noticed anybody has got injured thsat will go agsinst you withdraw immediately.
