Marlon Devonish claimed the men's 100m at the European Trials after Dwain Chambers pulled out with an injury.
Devonish is not sure whether to double up in Gothenburg
Devonish, who goes in his preferred 200m on Sunday, burst through to win in 10.19 seconds ahead of Tyrone Edgar with Mark Lewis-Francis third.
Chambers, the British number one, already has the qualifying mark and is likely to be given the nod by selectors despite not running in Manchester.
Jason Gardener also withdrew while Darren Campbell did not qualify.
"I was pleased with my performance but I don't know if I will double up yet," Devonish told BBC Sport.
I'm not prepared to take any risks which might jeopardise the rest of my season
"The plan was only to do the 200m but I'll have to ask my coach (Tony Lester) if he wants me to do the 100m as well."
Chambers, back from a two-year drugs ban, picked up a thigh injury in his semi-final.
"I'm not prepared to take any risks which might jeopardise the rest of my season," said Chambers, who has an impressive season's best of 10.07.
The 28-year-old was stripped of the European title he won four years ago following his suspension, if selected on Tuesday, he is favourite to regain his crown in Gothenburg.
Gardener, the British number one in Chambers' absence, pulled out after his heats because of a back injury.
"I thought it was best not to go out and do further damage that could set me back another five weeks," said Gardener.
"I'm going to try to concentrate on training and look forward to the end of the season and hopefully I can salvage something."
There was also an injury concern for Christian Malcolm, who injured his hamstring in the final and may now miss the 200m heats.
At the age of 32, Joice Maduaka set an explosive lifetime best to capture the women's 100m title.
The Londoner, who credited her win to now working with both Ron Roddan and Darrell Smith, roared out of the blocks to win in 11.23.
"It's taken forever and I'm over the moon," Maduaka told BBC Sport.
"This is just part of the journey and I've got a feeling that Gothenburg is going to be a good one for me."
Triple jumper Ashia Hansen returned from a two-year absence to finish second behind American Tiombe Hurd with a leap of 13.65m.
The 34-year-old suffered a career-threatening knee injury in June 2004 but has battled back after four operations.
Hansen's mark does not meet UK Athletics elite standard so she must wait to see if the selectors give her dispensation to compete in Gothenburg.
Turner hit form to win the 110m hurdles and celebrates in style
Greg Rutherford dominated the men's long jump competition and impressively saw off rivals Chris Tomlinson and Nathan Morgan with his final jump.
The 19-year-old landed 8.26m - just 1cm short of Tomlinson's British record - to climb to number two in the European rankings.
Tomlinson took second with 7.87m with Morgan a close third after landing 7.84m.
Andy Turner looked in sensational form as he effectively booked his place at the Europeans with victory in the 110m hurdles.
Helped by an assisting wind which invalidates the times, Turner clocked an impressive 13.24 ahead of former decathlete Will Sharman (13.45).
Sarah Claxton, who already has the elite standard for Gothenburg, claimed the women's 100m hurdles in 13.18.
Heptathletes Jessica Ennis, who set a personal best of 13.19 in the heats, and Kelly Sotherton finished fourth and fifth respectively.
Cross-country specialist Peter Riley ran a new personal best of 13 minutes 46.68 seconds to claim a surprise win in the 5,000m.
Riley's time is outside the European qualifying mark but was good enough to edge out Mo Farah and Nick McCormick, who has already achieved the qualifying time this season.
Commonwealth bronze medallist Steve Lewis won the pole vault in 5.40m while Goldie Sayers took top spot in the women's javelin with 58.81m - both were outside the required qualifying standard.
Blackpool's Carl Myerscough won the shot put with a throw of 20m, exactly the elite standard he needed to book his ticket to Sweden. He then went on to wrap up the discus title after landing 61.04m.
Ireland's Deirdre Ryan hit the qualifying mark of 1.92m to win the high jump ahead of Julie Crane (1.86m) and Ennis (1.82m).
There was also more encouraging news for Tim Benjamin as he ran a season's best of 45.92 to advance to Sunday's final of the men's 400m.
