Washington Redskins tight end Fred Davis was suspended indefinitely without pay on Wednesday for violating the NFL's substance abuse policy.

The suspension begins immediately.

Davis, 28, is set to become a free agent in March. He previously served a four-game suspension for a failed drug test in 2011.

Davis said Wednesday the suspension stems from a supplement he took that contained a banned substance.

"In the past, I made the mistake of knowingly ingesting a banned substance," he said in a statement. "For over two years, I've worked very hard to eliminate marijuana from my life, and I have not had a positive test for it since 2011. Unfortunately, a couple of months ago I took a supplement that contained a banned substance. I now know that supplements are not regulated by the FDA and may contain banned substances.

"The NFL policy is strict, and not knowing that a supplement might contain a banned substance doesn't excuse a violation of the policy. I've worked closely with the NFLPA and NFL to resolve this violation, and I will be permitted to apply for reinstatement in the fall. I look forward to staying in football shape, remaining in compliance with the NFL policy, and having a chance to get back on the field to contribute to a team's success next season."

Davis had just seven catches for 70 yards with a touchdown in 10 games in 2013.

---Offensive line coach Jim Turner will stay away while the rest of the Miami Dolphins' staff is in Indianapolis this week for the NFL Scouting Combine.

Turner's job status appears to be uncertain after his name emerged in the report on the Dolphins' workplace issues by investigator Ted Wells. According to the report, Turner was involved in the harassment of Miami players and staff and was not truthful with investigators when they questioned him.

The report also indicated that Turner tried to get offensive lineman Jonathan Martin to publicly defend teammate Richie Incognito. Martin left the team in October because of the alleged harassment.

---The Dallas Cowboys will pick No. 16 in the first round of the NFL Draft in May.

The Cowboys won a coin flip with the Baltimore Ravens that took place at the NFL Scouting Combine in Indianapolis to break a tie. The Ravens will have the No. 17 overall selection, which is their highest pick in the draft since 2008.

Both teams finished the regular season with 8-8 records and had identical strength of schedule ratings. Their 2013 opponents' winning percentage was .484, necessitating the coin flip.

---Former Arizona Cardinals safety Kerry Rhodes spent the 2013 season out of football but does not think it has anything to do with rumors about his sexual orientation.

Rhodes, 31, was considered one of the NFL's top safeties in 2012 but could not land a job for the 2013 season. He believes it was more about his contract demands than his personal life.

"I don't think I was blacklisted," Rhodes told ESPN New York. "Especially with the NFL, I don't think they would do that. ... To me, it was a product of me wanting to do other things and not finding the right opportunity.

"I emphatically said no once (to the gay rumor) and that's all I need to say. And people who know me know that's definitely not the case. To me, I'm definitely not and I can't control what people think, so I move on."

---The Washington Redskins confirmed that cornerback DeAngelo Hall re-signed with the team.

The Redskins did not release details of the contract, but reports indicated that it was a four-year deal worth approximately $5 million per season.

Hall, 30, led the Redskins with four interceptions and three defensive touchdowns in 2013 while also recording 78 tackles and two forced fumbles. He was the first Washington player to score three times on defense (two interceptions, one fumble return) in history.

---After watching former Texas A&M quarterback Johnny Manziel in college, Brett Favre understands the comparisons between the two.

Favre was impressed with Manziel after watching him play on Oct. 12 in the Aggies' 41-38 win over Mississippi. In that game, Manziel completed 31 of 39 passes for 349 yards and ran for 124 yards and two touchdowns.

The 6-foot Manziel is not as big physically as the 6-2 Favre, but his style of play and the ability to improvise are similar. Favre says Manziel is a better passer at this stage of his development that he was.

---Baltimore Ravens running back Ray Rice "struck Janay Palmer (his fiancee) with his hand, rendering her unconscious" according to the summons issued in Atlantic City Municipal Court on Wednesday.
