What wildlife would do this

I have 2 veg patches with a say 1.5m (5ft) grass path between.  Among other things (sweetcorn,  onions & courgettes) there's a row of DFB. This morning about 9am I walked around to check on things and in the middle of the grass path was an uprooted DFB. It had come from about 3ft in from the end of the row and was deposited in line with the row of beans.  I think it might have happened during the morning rather than overnight as it hadn't wilted much. It wasn't nibbled and beans were attached and untouched. I'm puzzled.  I'm wondering whether pigeon, bunny or cat might have got entangled.  There are no other sign of nibbling so I don't think I've got another rabbit.
