The Miami Dolphins have suspended Pro Bowler Richie Incognito after allegations of misconduct lodged by linemate Jonathan Martin, who left the NFL team last week in the middle of the season.

Incognito was suspended “for conduct detrimental to the team.”

“We believe in maintaining a culture of respect for one another,” the Dolphins said in a statement.

Last week, the Dolphins announced Martin had taken “a leave of absence.”

“Shame on you for attaching my name to false speculation,” one of the tweets said, according to Bleacher Report. That tweet and others addressed to various media outlets were deleted later.

Last week, the Dolphins announced Martin had taken “a leave of absence.” At the time, the team said Martin had made no allegations of bullying.

The team said Sunday it had asked the NFL “to conduct an objective and thorough review.”
