Jonathan Tiernan-Locke is facing disciplinary proceedings after analysis of his biological passport showed an anti-doping violation.
The Team Sky rider pulled out of the 2013 World Championships in September after being asked to explain his results by the UCI.
The Briton has "vehemently" denied any wrong-doing.
Team Sky released a statement on their website, reiterating their belief that Tiernan-Locke rode clean during his time with Team Sky:
"Jonathan Tiernan-Locke will not ride for Team Sky or take part in any team activities – including training camps and all team duties – until a decision is made in this disciplinary hearing process.
"We understand that the violation was highlighted by an anomaly in his biological passport, in a reading taken before he signed for this team.
"There are no doubts about his approach or performance in Team Sky. This is a team that trains, races and wins clean."
