The Miami Dolphins told Richie Incognito to toughen up Jonathan Martin, but they did not tell Incognito to bully him, according to a report from the South Florida Sun-Sentinel.
Incognito was recently banned indefinitely from the Dolphins squad following revelations that he bullied and racially abused Martin.
Now a report has suggested that the chain of events started when unnamed Miami coaches approached Incognito and asked him to 'toughen up' Martin after the player missed a voluntary workout session last spring.
Incognito has been accused of texting racial abuse to Martin whilst also threatening to harm members of his and said he would defecate in Martin's month if given the chance.
Joe Philbin has already taken responsibility for the incident but will no doubt land in deeper trouble if the revelations are true.
Philbin earlier said that anything that happens to his player under his watch is his responsibility.
"I want you to know as the head coach of the Miami Dolphins I am in charge of the workplace atmosphere," Philbin told reporters.
"Since April 10, 2012 when the players first came here and I was the head coach, every decision I've made and everything we've done to the facility has been done with one thing in mind, and that is to help our players and our organisation reach their full potential.
Any type of conduct, behaviour that detracts from that behaviour is not acceptable and is not tolerated."
