Stewards are yet to set a date to resume an inquiry into Hugh Bowman's Epsom Handicap-winning ride.

Bowman was one of three jockeys to front stewards at Randwick on Saturday as stewards opened an inquiry into an incident on the home turn.

Stewards found Bowman's mount Winx had to be checked before she was able to get into clear and sprint away with the $1 million race.

Blake Shinn's mount Kirramosa was put off balance during the incident and stewards also questioned Sons Of John's rider Jeff Penza.

Stewards say they are concerned about the positioning of Bowman's elbow as he attempted to to make his run on Winx.

"We're looking at re-opening the inquiry later in the week," deputy chief steward Greg Rudolph said.

Video footage shot from a raceday helicopter will be analysed before the inquiry resumes.

"We are trying to enhance the picture from the chopper shot as well as from the camera on the home turn," Rudolph said.
