Team Katusha’s Kim Kirchen is said to be in a stable condition in hospital after suffering a suspected heart attack on Friday evening after completing Stage 7 of the Tour of Switzerland.

The rider, from Luxembourg, finished in seventh place overall in the Tour de France in both 2007 and 2008, and in the latter year wore the race leader’s yellow jersey for four consecutive stages.

According to a statement on the Team Katusha website, “based on the tests done until now, it is possible to exclude both a infarctus or a thrombosis. The statement added that the 31-year-old, who who in 2008 won La Flèche Wallonne, would “remain in this state during at least the next 24 hours. Further communications will follow as soon as possible.”
