Team Sky are desperately sad to report the death of carer Txema González, aged 43.
Team principal Dave Brailsford spoke for the whole of Team Sky when he said: "We are devastated to report that Txema tragically passed away on Friday evening in hospital in Seville. His close family were with him."
Team Sky's Head of Medical Dr Steve Peters explained: "Txema contracted a bacterial infection which entered the bloodstream and developed into sepsis.
"The toxins from this had damaged the organs in his body and he went into septic shock and unfortunately succumbed to that.
"I should also clarify that this bacterial infection has nothing to do with the viral infection which many of the team have suffered with in Spain, causing stomach upset."
Brailsford paid tribute to a hugely popular member of the Team Sky staff, adding: "Txema will be remembered as a warm-hearted colleague who was a joy to work with and was universally respected by our team and throughout the pro cycling scene.
"Our thoughts are with his family and friends."
A minute's silence will be held in memory of Txema on Saturday before the start of stage eight of the Vuelta a España.
