Australia's Malcolm Page and Mat Belcher face a nervous wait after their men's 470 dinghy medal race was postponed at the Olympic regatta because of light winds.
The pair are hoping to win the 470 gold medal and hold a four-point lead over British pair Luke Patience and Stuart Bithell.
The medal race was due to get underway at 1pm BST (10pm AEST) on Thursday, but light winds forced organisers to postpone the showpiece final for several hours.
The windspeed, which at 11am BST (8am AEST) was only about two or three knots, will now be monitored to see if the race will be staged on Thursday.
If not, it will be held on Friday or Saturday.
