centerstand

Bike got knocked over. Either the kickstand somehow snapped on its own and it just fell (which seems super unlikely) or someone backed into it without leaving a mark on that side of the bike . Kickstand I need asap as the bike is basically leaning against a wood board atm so will be buying...

The manual states to check chain slack on the centerstand. Presumably checking slack on a paddock stand would throw off the measurement seeing as the swing arm would not be hanging as if it were on the center stand. My bike does not have a centerstand. How do you guys who don't have centerstands...
