TRAGEDY has again struck Adelaide with captain Taylor Walker and his partner Ellie mourning the loss of their unborn baby.

The terrible news comes less than three months after vice-captain Rory Sloane and his wife Belinda lost their first child Leo, who was stillborn.

Walker, who was due to return to pre-season training next Monday, will take time away from the club as he deals with the heartbreaking situation.

"Adelaide has granted Taylor Walker personal leave following the loss of he and his partner Ellie’s unborn baby," the Crows said in a statement on Thursday night.

"The thoughts of the entire Crows family are with Taylor and Ellie, as well as their extended family, at this difficult time.

"The club asks that their privacy is respected and there will be no further comment at this stage."

Walker, 28, has captained the Crows since 2015. Later that year, he displayed tremendous courage in helping the club deal with the tragic loss of coach Phil Walsh.

Walker has played 167 games for the Crows.
