Jaguars coach Jack Del Rio dismissed middle linebacker Mike Peterson from the team's headquarters on Wednesday. Del Rio would not divulge the specific incident for which Peterson was being disciplined.
"Mike Peterson was sent home today and did not practice. We're working through this process seeking an appropriate conclusion," Del Rio said.
Jaguars.com has learned that Del Rio took exception to a sack celebration by Peterson in the third quarter of this past Sunday's game in Cincinnati when the Bengals led, 21-3, though there was no sideline exchange between the two. The root of the discord, however, is thought to be the result of Peterson's contract discontent.
Del Rio also expressed disapproval on Wednesday of defensive tackle John Henderson's behavior as he left the field following his expulsion from Sunday's game, and Del Rio took exception to loud laughter in the Jaguars' postgame locker room media period. Henderson mocked jeering Bengals fans as he left the field.
"Those are some of the things I've addressed, privately, that are not a good reflection of me and what I stand for and, in many ways, I take pride in the fact that this team is a reflection of me and I want it to be a reflection of me and I don't like that reflection. I don't like those types of things," Del Rio said on Wednesday.
Del Rio would not comment on Peterson's status beyond Wednesday.
