In a mixed day for apprentices, Brenton Avdulla fell ill after riding the first two winners at Randwick, Tim Bell also had a double while Jamie Quinnell and Mitchell Beadman were no-shows at the meeting.

Chief steward Ray Murrihy spotted that Avdulla wasn't well at an inquiry into the youngster's winning ride in the opening race of the day on Devils Arcade ($3.70) for trainer Gai Waterhouse in the Sharp Handicap (1800m).

Avdulla later rode the David Payne-trained Star Lass ($31) to victory in the Sydney City Toyota Handicap (1000m).

Devils Arcade rocketed to the lead before Avdulla pulled her back near the 800 metres, resulting in the hoop being forced to dig the filly up again and it was this move stewards inquired about.

After being satisfied that Avdulla had made a minor error in judgment, Murrihy's attention turned to Avdulla's health.

"Are you okay," Murrihy said.

"I'm feeling pretty ordinary," Avdulla said.

Avdulla, who is on a two-month loan to Waterhouse, began his time with the trainer in the best possible fashion with a win aboard Dance Idol at Canterbury on October 7.

Tamworth-based apprentice Timothy Bell capped off a great week with victories on Big Red Cat and Dorf Command.

Bell celebrated his first stakes win on Thursday when he scored on Beaded for trainer Peter Snowden in the Listed Yalumba Cup at Hawkesbury.

Meanwhile, the career of Beadman is at the crossroads after he was sacked by his fourth master Chris Waller and as a result the youngster did not ride at Randwick where he had commitments.

Murrihy spoke with Beadman on Saturday.

"I talked to him this morning. There's obviously been some issues between him and his master. I'll be talking to him (Beadman) on Monday, there's no future for him with Mr Waller and he's had four masters now, so there is some sort of problem," Murrihy said.

John Hawkes, Kevin Moses and John O'Shea were Beadman's former masters.

Beadman has to satisfy Racing NSW that his riding techniques and practices conform to the new whip rules before he is permitted to ride again.

On Tuesday, he was handed a two-day suspension, on November 11 and 12, and referred to the panel.

He pleaded guilty to two charges of breaking the whip rules at the Rosehill meeting on October 24.

Quinnell was a no-show at Randwick where he had riding engagements before starting a lengthy ban for drug use.

He didn't show up to trackwork on Saturday morning and his master Kevin Moses informed stewards at 8:51am (AEDT) that the young rider could not be contacted.

Quinnell was given a lengthy suspension on Friday after testing positive to a banned substance.

He pleaded guilty to a breach of AR 81A at a Racing NSW hearing.

A sample was taken from Quinnell after he rode at the Warwick Farm meeting on October 5 and the rider pleaded guilty to a breach of the rule at a Racing NSW stewards' hearing on Friday.

His apprentice permit will be suspended until January 1 next year which means he will not be permitted to ride trackwork or in barrier trials until that date.

Quinnell's licence to ride in races will be suspended until June 8.

However, that ban will be reduced to April 8 if he completes a satisfactory period of professional counselling.
