Western Bulldogs skipper Easton Wood copped a hit at Adelaide Oval that he hopes he'll never experience again.

On the stroke of halftime in Friday night's clash against Adelaide a male home team fan leaned over the boundary fence and gave Wood a firm slap on the backside.

A clearly displeased Wood turned around and glared at the errant patron but jogged away.

"I certainly wasn't expecting it at all," Wood told Channel Seven's Game Day.

"I didn't say anything ... I certainly wasn't hurt or anything like that.

"But I was a bit surprised.

"My preference would be to be able to go to work and not get slapped on the arse by a complete stranger.

"I'll be fine but hopefully it doesn't happen again."

Fan contact with players is a clear no-no and Crows and stadium management are investigating the incident.

The Bulldogs suffered a 37-point loss to Adelaide that left them in 13th place with a 4-5 record.

The match was Wood's first back from a hamstring injury suffered in round seven.

"I didn't actually think about that at all during the game, which is a good sign," he said.

"It was good to get through the game unscathed."
