DAVIE, Fla. (AP) -- Suspended Miami Dolphins guard Richie Incognito sent text messages to teammate Jonathan Martin that were racist and threatening, two people familiar with the situation said Monday.
The people spoke to The Associated Press on condition of anonymity because the Dolphins and NFL haven't disclosed the nature of the misconduct that led to Incognito's suspension.
Martin, a tackle, remained absent from practice Monday one week after he suddenly left the team. Also missing was Incognito, suspended indefinitely late Sunday by Miami for his treatment of Martin.
The team and NFL continued their investigation into allegations by Martin's representatives that he was bullied, and Dolphins coach Joe Philbin said it was Miami owner Stephen Ross who asked league commissioner Roger Goodell for assistance with that probe. The NFL Players Association also planned to look into the matter.
"Since April 10, 2012, when the players first came here and I was the head coach, every decision I've made, everything we've done in this facility has been done with one thing in mind," Philbin said Monday. "That's to help our players and our organization reach their full potential. Any type of conduct, behavior that detracts from that objective is not acceptable and is not tolerated."
The 319-pound Incognito, a ninth-year pro, is white. The 312-pound Martin, who is in his second NFL season, is black.
It's unclear whether Dolphins coaches and management had any inkling of harassment between players before Martin left the team, and Philbin declined to answer a question about the locker-room culture because of the ongoing investigation. Recent rumblings of locker-room dissension have also included complaints by young players that they're pressured to pay more than their share when team members socialize together.
Philbin also said he was unaware of hazing incidents that involved Incognito - such as hacking into a teammate's Facebook page - on the HBO series "Hard Knocks," which chronicled the Dolphins' training camp in 2012. Philbin said he never watched the show.
"If the review shows that this is not a safe atmosphere, I will take whatever measures are necessary to ensure that it is," Philbin said. "I have that obligation to the players that I coach on a daily basis and I will do that."
Before being suspended, Incognito posted several tweets saying he wanted his name cleared.
"Three things cannot be long hidden: the sun, the moon, and the truth," Incognito tweeted, quoting Buddha.
Agents for the two players didn't respond Monday to requests for comment. Martin is with his family in Los Angeles for counseling.
Incognito has long had a reputation as one of the NFL's dirtiest players. During his first four years, he led the league in penalties for unnecessary roughness, and the St. Louis Rams got fed up with his undisciplined play and released him during the 2009 season.
"There's certain people out there who are just punks, and he wants to be that kind of guy," former Seahawks and Lions defensive end Lawrence Jackson said Monday. "But because he's a lineman, he gets away with a lot of stuff that people don't see. ... Incognito is way worse than anybody I ever played against."
However, there have been fewer such complaints since Incognito joined the Dolphins in 2010.
Last year he was voted by the league's players into the Pro Bowl for the first time. He was the co-winner of the Dolphins' Good Guy Award, given to the team's most cooperative player by the local media. He also won frequent praise from Dolphins coaches for his leadership, and this year he was voted by teammates to serve as a member of the Dolphins' player council.
Philbin said the Dolphins had a team meeting on the matter. Predictably, it was not a topic many players wanted to say much about.
"I'm concentrating on football," Dolphins defensive end Cameron Wake said.
At Nebraska, Incognito's career was cut short when he was suspended in 2004 before his junior season following a locker room altercation with a teammate. He also ran into problems with the law while with the Cornhuskers, and they said he repeatedly violated team rules.
Martin protected Andrew Luck's blind side at Stanford before joining Miami as a second-round draft pick in 2012. He has been a starter since the beginning of his rookie season, but has struggled while dividing his time between left and right tackle.
"I can only answer for myself, and yes, I would," tight end Michael Egnew - the player whose Facebook page was hacked by Incognito - said when asked if he would welcome Martin back to the team.
For the first six games this year, Incognito and Martin were the two players protecting Ryan Tannehill's blind side, which may help explain his league-high 35 sacks.
"I think laughter can be a healthy, productive thing," Philbin said. "But not in a demeaning way at the expense of an individual."
