Blues coach John Kirwan has called his team's 14-man effort against the Stormers brave, but has conceded the ill-discipline, which began with Hayden Triggs' red card for punching after 24 minutes, cost them victory.
The Blues went down 27-16 to the Stormers in Cape Town this morning, Triggs' sending off for striking Duane Vermeulen in an apparent act of retaliation extremely costly.

The score was 8-6 to the Stormers at the time, with Nic Groom darting around a ruck to score for the home side, and the Blues let another try slip when Dillyn Leyds fielded a high kick and went in from 55m to push the halftime score out to 18-9.
However, they rallied in the second half, outscoring the Stormers 10-9 despite their numerical disadvantage, and they were probably unlucky not to get a losing bonus point at least.
