HURT* - данный глагол является неправильным и всё его формы прошедшего времени одинаковы (hurt-hurt-hurt). В данном случае контекст не даёт возможности понять в каком времени стоит глагол. Поэтому, если в прямой речи глагол стоит в настоящем времени, то в косвенной речи останется hurt. Но если же данный глагол в прямой речи стоит в прошедшем времени, то в косвенной речи будет had hurt.
