MIAMI -- The NFL Players Association said it will insist on a fair investigation for all involved in the Miami Dolphins harassment case, including suspended guard Richie Incognito. Air Force 1 Promo . 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 by coach Joe Philbin for his treatment of Martin. "As the representative organization of all players, the NFLPA will insist on a fair investigation for all involved," the union said in a statement Tuesday that included no condemnation of Incognitos conduct. Instead, the union said accountability rested with the Dolphins. "We expect that the NFL and its clubs create a safe and professional workplace for all players, and that owners, executives, coaches and players should set the best standards and examples," the union said. "It is the duty of this union to hold the clubs ... accountable for safety and professionalism in the workplace. ... We will continue to remain in contact with the impacted players, their representatives and player leadership." Incognito, speaking publicly for the first time since his suspension Sunday, was interviewed briefly by a reporter for WSVN-TV. "Im just trying to weather the storm right now," Incognito said before getting into his car. "This will pass." Dolphins officials didnt respond to requests for comment. The team practiced Tuesday for its game Monday night at Tampa Bay, but had no media availability. Incognitos harassment of Martin included text messages that were racist and threatening, two people familiar with the situation have said. The 6-foot-5, 312-pound Martin, a second-year pro, is biracial. Incognito, a guard in his ninth NFL season, is white. The case leaves the 30-year-old Incognitos career in doubt, and an associate professor at the University of Miami School of Law said he could face criminal charges. "This can be pursued as an extortion case," Tamara Lave said. "It could also be pursued as making some kind of threat against the other players life. ... This particular cultural moment is one in which people are very upset about bullying and hazing. ... I think that prosecutors may think its important for them to do something. And the fact that you have a 300-pound man who feels so threatened and uncomfortable that he leaves, thats an indication of how serious it was." No criminal investigation has been disclosed. Meanwhile, the NFL must decide whether the Dolphins failed to enforce the guidelines for workplace conduct included in the leagues player policy manual. "All NFL players and prospective players have the right to work in a positive environment that is free from any and all forms of harassment, intimidation and discrimination," the manual says. Every player receives a copy during training camp. Coach Joe Philbin said he was unaware of any harassment between the players until after Martin left the team. The Stanford graduate is with his family in Los Angeles for counselling, and its unclear whether hell rejoin the team this season. Also unclear is how other players would receive Martin after he complained about a teammate and abruptly left while Miami was mired in a four-game losing streak. The Dolphins shored up their depleted offensive line by signing David Arkin off the Dallas Cowboys practice squad. "I hope that Martin doesnt have any backlash from this from the rest of his teammates," said Arizona linebacker Karlos Dansby, who played for the Dolphins from 2010-12. Dansby said he was puzzled that Martins teammates didnt put a halt to any harassment. "Were like family. So why would we do something to hurt our family? I dont understand it. Definitely you have to step in and say something. Unfortunately the guys didnt step in down there. You got to have leaders step and up and control that kind of situation." Around the league, a handful of players had harsh words for Incognito, long considered one of the dirtiest players in the NFL. Some players defended the tradition of hazing, while others said it needs to change. Seattle Seahawks coach Pete Carroll supported the latter view. "We dont allow hazing here," Carroll said. "In the past, yeah, Ive seen it. Its just an old-school way of thinking and a way of operating. We know better now."

Running routes felt great.McDonald hurt his knee during the 49ers loss to the Chicago Bears two weeks ago and has been limited to personal training as established by the team trainers.Its something I had to work through, McDonald said. Weve been using caution; its all about Sunday.The second-year tight end said he did well at Fridays workout, which tested his knee from every angle.Im pretty happy, McDonald said. I was impatient and wanted to do more work after I was finished for the day, but the trainers kept me on a schedule and theyve done a great job of getting me back in a timely fashion.McDonald, who has one catch for 9 yards on the season, would give the 49ers more options. They relied on a five-receiver set in last weeks loss to the Arizona Cardinals because of a lack of depth at tight end.Thats what I like about this team: we can line up two tight ends or go with a five-receiver set and still move the football, McDonald said. I thought they did a great job offensively.Davis refused to commit to playing, perhaps shying away after making a definitive statement last week and not playing.It will be more of a game-time decision, Davis said. Well keep working and hopefully I can be ready. I feel a lot better than last week.Davis is sore in the deltoid ligament region of his ankle, which is the area where the foot and leg meet. He said he feels it around the front of his ankle and will test it Sunday about an hour before game time.Its tough when the guys are all out there battling, Davis said. Destockage Air Max. . You want to be out there with them. But you cant get too overwhelmed. Ill just take it one day at a time.49ers coach Jim Harbaugh also expressed caution and optimism about Davis status, while extolling his talents in all phases of the offence.Hes one of the rare tight ends thats really good in the run game and really good in the pass game, Harbaugh said. Hes at the highest level in both.Davis also realizes his value as a run blocker.Definitely, when you can run or pass everyone gets a chance to get involved, especially Frank Gore, Davis said. We cant do too much without him. Weve got to get him going as well as Michael Crabtree and the other receivers.NOTES: Harbaugh said the reason a field goal attempt was blocked against the Cardinals, who only had nine men on the field at the time, was that half the team never got the signal that a fake was taken off. We didnt communicate the fake was off, he said. Half the line knew it was off and half the line was blocking like it was a fake. ... LB Patrick Willis said he never prepares anything ahead of delivering his pre-game speech each week. Its just something I feel during warmups as I look at the team, he said.
