"We tried to handle this situation with Brandon as privately and professionally as we could throughout the entire process with he and his agent, Kennard McGuire," McDaniels said at a news conference. "This morning, we made the decision as an organization to go ahead and suspend Brandon. We'll look forward to having him back on Sept. 6th as we begin our preparations for Cincinnati" in a Sept. 13 opener.McGuire didn't immediately return a phone call Friday. McGuire was out of the country until Monday.
McDaniels did not single out a specific episode but said the suspension resulted from a series of incidents, though some boorish antics during the team's practice Wednesday
- after he had been warned about such conduct that very morning - seemed to be the final straw for the coach.
"His actions didn't really change after that warning. That leads us to today," McDaniels said.
During pre-practice warmups Wednesday, Marshall walked while the rest of the team ran. He punted a ball away instead of handing it to a ball boy and swatted a pass thrown to him. His actions were caught on video and broadcast by KMGH-TV.
Marshall told ESPN on Thursday night he wasn't trying to force a trade through insubordination but that frustration got the best of him.
Marshall, who had 206 receptions the past two seasons, is also upset with what he feels was the team's misdiagnosis of a hip injury that required offseason surgery. He pulled a hamstring during the first weekend of training camp and didn't return until a week ago.
Fellow wide receiver Brandon Stokley said he wasn't surprised the Broncos temporarily banished Marshall.
"Not really, not with his attitude and how he was acting," Stokley said. "Something had to be done. They made the decision. We're moving on, and hopefully in a few weeks, when he's back, he'll be ready to contribute."
Daniel Graham was concerned enough about Marshall's behavior at practice that the tight end said he talked to him about it several times. He said his main concern now is to make sure it doesn't become a distraction to the team.
"We've had a few conversations and Brandon, he's running his own ship," Graham said. "He's doing what he feels is best for him. Now, I'm just making sure, as a leader on this team, that we stay focused."
Marshall was held out of practice Thursday, apparently as the organization was formulating its disciplinary response.
"We're trying to handle this in a way that we can discourage this from happening," McDaniels said. "We didn't want to be in this situation. We never wanted it to get to this point. I'm sure they didn't either."
For all the tension and disagreement between the receiver and his coach and organization, McDaniels said he hasn't given up on the notion that the sides can work things out.
