Musselburgh's Friday jumps fixture has been cancelled due to frozen ground.
An inspection was set to take place as early as 8am this morning, but Harriet Graham (Clerk of the Course) made an instant call after temperatures reached well below freezing overnight.
(Credit: Racing Post) Graham said: "Ground temperatures hit a low of -6.9C last night so there was quite a lot of frost to come out.
"Temperatures today are only set to reach 2C or 3C by noon so there is just not enough time, hence we made an early decision," she said.
So with Musselburgh off, the jumping action takes place at Chepstow this afternoon, plus all-weather action at Lingfield that kicks off at 12:55.
Kempton and Dundalk commence their twilight cards at 4:10 and 5:30 respectively, for a night under the lights.
