"Browns receiver Donte' Stallworth was suspended indefinitely by NFL commissioner Roger Goodell on Thursday, two days after Stallworth pleaded guilty to DUI manslaughter and began serving a 30-day jail sentence.

In excerpts of his letter to Stallworth released by the NFL, Goodell said Stallworth's ''continued eligibility'' would ''undermine the integrity of and public confidence in our league.''

The commissioner said he will eventually meet with Stallworth and levy a more specific suspension. Until then, Stallworth will be prohibited from visiting the Browns' facility or participating in team activities after he is released from a Miami jail.

An indefinite suspension against Adam ''Pacman'' Jones in October, 2008 was later amended to six games.

Browns General Manager George Kokinis said in a statement: ''We support the action taken by the commissioner today and will continue to work closely with the league regarding this matter.''

Stallworth was driving with a blood-alcohol level of .126, over the Florida limit of .08, when he struck and killed pedestrian Mario Reyes, 59, on March 14 in Miami Beach.

Goodell sounded terse in his letter to Stallworth.

''The conduct reflected in your guilty plea resulted in the tragic loss of life and was inexcusable,'' Goodell wrote. ''While the criminal justice system has determined the legal consequences of this incident, it is my responsibility as NFL Commissioner to determine appropriate league discipline for your actions, which have caused irreparable harm to the victim and his family, your club, your fellow players and the NFL.

''The conduct that led to your conviction plainly violates both the Personal Conduct and Substances of Abuse policies. Either provides me with full authority to take appropriate disciplinary action against you, including a fine or suspension without pay, and to impose appropriate conditions on your continued participation in the NFL. In this case, there is ample evidence to warrant significant discipline under both policies.''

Goodell made a reference to ''favorable treatment,'' which could have been in response to the public outcry over what appeared to be a lenient sentence in Stallworth's plea bargain.

Stallworth will remain under probation for 10 years, the first two under community control, which would allow him to work without electronic monitoring, according to his attorney, Christopher Lyons. Stallworth is also prohibited from driving for life, per Florida statute, although he can apply for a hardship license after five years."
