Yohan Blake believes IAAF president Sebastian Coe is "killing" athletics by cutting back on Diamond League disciplines.
Sweeping changes announced in November saw the 200 metres, 3,000m steeplechase, discus and triple jump removed from the schedule for the upcoming season in a bid to accommodate a 90-minute broadcast window.
Former 100m world champion and 200m Olympic silver medallist Blake thinks the decision will do more harm than good to the sport.
"It has changed a lot, I am not going to lie. The times we are running have slowed down, track and field is dying a little," said Blake.
"If [Coe] can take away the 200 and triple jump, I don't know if he is trying to build or trying to kill athletics.
"But that's a stupid move he is making. He must enhance the sport, but he is killing it. It is just madness.
"This is people's careers and where they make money… You cannot do that. Everybody is hating him. We have to take a stand."
