The NFL Players Association says it will insist on a fair investigation for all involved in the Miami Dolphins harassment case, including suspended guard Richie Incognito.

The league is investigating the relationship Incognito had with teammate Jonathan Martin, who left the team last week because of emotional issues. Incognito was suspended indefinitely Sunday by coach Joe Philbin for his treatment of Martin.

In a statement Tuesday, the union said accountability rests with the Dolphins.

Incognito spoke publicly for the first time since his suspension when he was interviewed briefly by a reporter for WSVN-TV. He said he's just trying to weather the storm right now, and this will pass.

The Dolphins practiced Tuesday for their next game but had no media availability.
