Cofidis boss quiet over Di Gregorio doping allegations
Cofidis team boss Yvon Sanquer has refused to comment on reports French rider Remy Di Gregorio has been taken by police from the Tour de France to Marseille for questioning over alleged doping offences.
A media conference will be held at the team's rest-day hotel in Bourg-en-Bresse at 4pm local time.
The 26-year-old from Marseille rode for Francaise des Jeux before spending 2011 at Astana and subsequently joining Cofidis for the 2012 season.
Di Gregorio was 35th after stage nine's time-trial to Besancon, 18 minutes and seven seconds behind race leader Bradley Wiggins (Team Sky).
The Cofidis team withdrew from the 2007 Tour after Cristian Moreni failed an anti-doping test during the race. Wiggins was part of the team at the time.
