Injured Tony McCoy will not be in competitive action until next week after his bad fall at Worcester on Thursday.
The 18-times champion jockey was dramatically unshipped from the Rebecca Curtis-trained Keep Presenting at the first flight of the Injured Jockeys Fund 50th Anniversary Maiden Hurdle.
Keep Presenting jinked badly left and also brought down the Noel Fehily-ridden St Johns Point in the process, with McCoy also getting a kick for his troubles.
The star jockey received lengthy treatment from Worcester's medical team, but he was able to walk into an on-course ambulance for further treatment and fortunately escaped serious injury.
McCoy, who earlier this week anticipated not taking time off until Christmas, will nonetheless have a small spell on the sidelines.
He tweeted: "Feeling fairly sore this morning after my fall yesterday. "Won't be back riding until after the weekend - he (Keep Presenting) got me good."
McCoy was due to ride at Newton Abbot yesterday, where the track honoured him in recognition of the fact he rode more winners at the venue than any other on his way to his landmark 4,000th career success.
A bronze sculpture was unveiled in the weighing room before the first race.
Meanwhile Groovejet can take full advantage of a handy pull in the weights to give Peter Chapple-Hyam a first success in the Betfred Cesarewitch at Newmarket.
The three-year-old comes into the race in excellent form following a five-length second in the Group Two Park Hill Stakes at Doncaster, after which her official mark was boosted to 101.
However, due to the entry system, Groovejet will be lining up off a perch of 96 which gives her 5lb start on some of her main rivals and makes her a leading player.
Her Doncaster effort marked the culmination of a series of fine performances, including a place in Listed company and a fair fifth behind Missunited in a Group Three event at Glorious Goodwood.
She kept on resolutely when stepping up to just short of a mile and seven furlongs on Town Moor and while there is a bit of a question mark over her stamina for this two-and-a-quarter-mile test judged on pedigree, she was certainly not stopping at the finish.
With the very capable Franny Norton in the plate, she has plenty in her favour and can make hay from near the foot of the weights.
Supplicant showed signs of a revival when second to the reopposing Spinatrix at Ripon and he can emerge on top in the Coral Sprint Trophy at York with Jack Garritty on board..
