NFL commissioner Roger Goodell is seriously studying the Adam Jones altercation from last week and weighing what he feels would be the most appropriate action to take.

Dallas Pro Bowl cornerback Terence Newman underwent groin surgery on Friday and is expected to miss about a month, according to a Cowboys source.

Those waiting for an answer on whether the league will suspend Cowboys cornerback Adam Jones will have to wait.

The league’s review of the Jones matter will not be completed until next week.

Bad — but not unexpected — news for Adam Jones and the Dallas Cowboys. The NFL is investigating the incident the star cornerback was involved in at a Dallas night club early Wednesday morning.

Cowboys inactives: CB Terence Newman, WR Sam Hurd, WR Miles Austin, CB Courtney Brown, G Kyle Kosier, G Montrae Holland, OT Doug Free, LB Anthony Spencer.

Analysis: CB Adam Jones will start in Newman’s absence.

With Cowboys CB Terence Newman listed as questionable for Dallas’ opener against Cleveland, Adam Jones may be in a position to start in his first game for Dallas.
