blight tomatoes?

I'd put them in a tray and keep an eye on them for a few days to see if there are signs of blight having already infected them (brown blotches to start off with.)

If they had already reached a good size and were starting to show any signs of starting to ripen (usually a slight yellowing of the fruits) you might get them to successfully ripen, but again you need to keep a close eye on them for signs of rot.
