Half-centuries from Varun Chopra and Jeetan Patel lifted an under-strength Warwickshire side to 298 all out on the first day against Nottinghamshire at Trent Bridge.
The home side then capsized in the final five overs of the day to reach stumps on 14-3.
Chopra faced 114 deliveries and hit nine boundaries in his 76 before driving loosely at Luke Fletcher to provide Chris Read with one of his four catches, but the dismissal of the Bears' captain - at 125-3 - heralded the start of a mini-collapse which saw four wickets fall for just 11 runs.
Andre Adams, who was arguably back to something resembling his best after a season dogged by injuries, was the chief benefactor of Warwickshire's afternoon malaise, finishing with figures of 4-77, while Fletcher ended with 4-56.
Adams had made the initial breakthrough of the day, tempting Ian Westwood to feather an away-swinger through to Read, who gratefully completed the 900th dismissal of his career.
Although Ateeq Javid soon followed, fending Harry Gurney to slip for nought, the visitors lunched well on 103 for two but then ran aground as six wickets fell during the afternoon.
Fletcher removed Chopra and then had Steffan Piolet caught behind for just a single, after the batsman had been hastily summoned from Chester-le-Street where he was due to make his Sussex debut, on loan, against Durham.
Notts were gifted another wicket as Chris Woakes slipped over when responding to a call from Darren Maddy and was comfortably run out after smart work from Read.
Thirty-nine-year old Maddy made 47 a week after seemingly playing the final match of his county career, having been recalled to bolster a Bears side devoid of at least 10 first teamers due to a combination of injuries and international call-ups.
Patel scored an unbeaten 66, adding 88 with Peter McKay, who had an eventful championship debut.
The 18-year old wicket-keeper twisted an ankle early in his innings and had to bat with a runner on his way to making 33.
The home side loaned their second-team keeper, Matt Cross, to deputise for the injured McKay and he would have had the best view to witness Alex Hales being bowled first ball, leaving alone a delivery from Keith Barker.
Fletcher, sent in as nightwatchman, and Michael Lumb then perished to successive deliveries from Maurice Chambers, who himself played a second XI match for Notts three weeks ago, before completing a move to Edgbaston.
