Bruyneel leaves RadioShack
The RadioShack-Nissan team said the decision was by "mutual agreement," adding Bruyneel "can no longer direct the team in an efficient and comfortable way."
Bruyneel said he was leaving to "concentrate on my defense," having chosen an arbitration hearing to fight charges leveled by the U.S. Anti-Doping Agency.
Friday's announcement came two days after USADA's damning report on Armstrong exposed the doping program in the U.S. Postal Service and Discovery Channel teams that Bruyneel managed when Armstrong rode to seven straight Tour de France victories from 1999-2005.
