Tomlinson won silver at last year's world indoors
British long jump record holder Chris Tomlinson has become the fourth GB athlete to pull out of this weekend's European Indoor Championships in Turin.
Tomlinson has been struggling with an Achilles injury and feels he is not fully prepared to mount a challenge.
Kelly Sotherton cannot compete in the pentathlon because of a heel injury.
Long jumper Jade Johnson has a nerve problem in her take-off leg, while 1500m runner Chris Warburton has an injury to his right foot.
GB coach Charles van Commenee said: "By competing, they would have jeopardised their outdoor seasons."
Tomlinson, last year's world indoor silver medallist, said: "The indoors season hasn't quite progressed as I would have liked and I just feel I'm not in the right shape to do myself justice.
"I will focus on getting fit for my warm-weather training stint in San Diego and onwards for the outdoor season."
Sotherton, who won bronze in the 2004 Olympics and silver in the last European Indoor Championships, in Birmingham two years ago, has been struggling for some time and her withdrawal was no surprise.
Having had to miss the last two indoor meets, Sotherton said at the UK Indoor Grand Prix in Birmingham she was hopeful of making Turin, but asked the NIA crowd to "cross their fingers she would be fit".
Van Commenee added: "We have taken a cautionary route with all the athletes. Last week we believed Kelly would be able to make it but she suffered a reaction in a crucial training session on Monday morning and has made the decision to pull out."
Dwain Chambers, favourite for the 60m, will go head-to-head with Simeon Williamson and Craig Pickering, while Marilyn Okoro (800m) and Mo Farah (3000m) will also be in action after impressing in Birmingham.
The Championships start on Friday at the 6,600 capacity Oval Lingotto.
