Pretty much this, Swansons apparently told Coventry he wants a move back North, and was poised to move before one of their wingers (Maddison) got injured, once they have an agreement for a winger he'll be allowed to move. It seems to be between all three Tayside teams for him, although Uniteds pursuit of McKay maybe ended that.
Rotherham have offered to buy May outright, so youd assume the next few days that deal will be thrashed out with loan deals being forgotten about.
