New York, NY -- (Sports Network) - Dallas Cowboys cornerback Adam Jones has been suspended indefinitely without pay by the NFL for an alcohol-related altercation with a personal security guard at a Dallas hotel last week.

Jones will be suspended at least four games for violating his reinstatement arrangement, which expected the 25-year-old to refrain from any behavior that puts him, his team or the league in a negative light.

The Cowboys did not discipline Jones for Sunday's game against Arizona, but NFL commissioner Roger Goodell apparently gathered enough information to suspend the oft-troubled cornerback.

In a letter to Jones, Goodell described his findings as "a disturbing pattern of behavior and clearly inconsistent with the conditions I set for your continued participation in the NFL."

Before the season, Goodell reinstated Jones, formerly known by his nickname "Pacman," after a one-year suspension for violating the league's personal conduct policy. Jones, then with the Tennessee Titans, had numerous run- ins with the law in just two NFL seasons, including an alleged involvement in a shooting at a Las Vegas strip club during the NBA's All-Star weekend in February 2007. That incident left an employee of the club paralyzed from the waist down.

"We respect and support the decision of the commissioner," Cowboys owner Jerry Jones expressed in a released statement. "I regret that this issue has brought negative attention to the Cowboys and the NFL. We move forward with a very clear knowledge as to what the process will be for a possible re-instatement. Adam is well aware of where he stands and what he has to do."
