Dwain Chambers will run for Great Britain at the European Championships, provided he can prove his fitness.
Chambers was injured before the trials at the weekend
Chambers, returning from a two-year drugs ban, was left out of the initial 61-strong squad after missing the trials because of a thigh problem.
But the selectors have left a space vacant in the 100m.
UK Athletics performance director Dave Collins said Chambers would have to convince the organisation's medical staff he had recovered from the injury.
The final squad will be unveiled after the London Grand Prix at Crystal Palace on 28 July, with selectors having until midnight to submit the team.
Marlon Devonish, who won the 100m and 200m at the trials, decided to concentrate on the longer event.
Tyrone Edgar and Mark Lewis-Francis, who finished second and third behind Devonish at the trials, have been named in the 100m.
Chambers has clocked 10.07 seconds since his return to action, making him the second-fastest European this year, and Collins said he wanted a fully-fit athlete to travel to Gothenburg.
Darren Campbell has proved he is a first-class leader

"Dwain does not have to run necessarily to get in the team," said Collins.
"We would need to be convinced medically that he's on course to full fitness and can compete across a number of rounds.
"Taken that he is selected and he is fit, he is in with a good shout for a medal."
Veteran sprinter Darren Campbell may be given the chance to end his career on a high, with a potential place in the 4x100m relay squad after failing to qualify in the individual events.
"I think Darren has a genuine capability under fire to produce an effective performance and he has proved in the past he is a first-class leader," said Collins.
Meanwhile, Christian Malcolm, the quickest European over 200m this year, was injured on Saturday and is included subject to fitness.
Young 400m runner Martyn Rooney - who finished an impressive fifth at the Commonwealth Games - has not been included because he is competing at the World Junior Championships.
We are effectively giving some athletes one more chance
UK Athletics performance director Dave Collins
Triple jumper Ashia Hansen, the defending European champion, is also missing, but she may be given special dispensation because of severe injury problems and her strong record at the top level.
Jade Johnson is a notable omission in the long jump, with rival Kelly Sotherton, who also competes in the heptathlon, taking the place.
Collins said the squad was picked with a view to developing stars for the future, and warned some more established squad were being given "a final opportunity to prove they are capable of performing".
"The ability to combine developing athletes alongside elite in the selection process has given selectors the means to achieve three objectives," said Collins.
"(They are) to win medals, to use as a development opportunity for those with perhaps half an eye on Beijing and to give some athletes a final opportunity to prove they are capable of performing and effectively give them one more chance.
"In addition there are quite a few athletes selected who are not currently in receipt of world-class funding.
"For them this is a massive opportunity to show what they can do - one which will not present itself again for another few years."
Collins said he would like the team to come back with 10 medals.
"I think I'll stick with that stretch target," said Collins.
"There's been some good performances lately, but also some significant injuries."
