Aldon Smith's decision to seek alcohol treatment could work in his favor when the NFL decides whether to suspend him for his off-the-field issues.

Speaking to reporters after a forum for European fans, NFL commissioner Roger Goodell said that Smith's treatment will be considered when weighing any discipline.

"Yes, it will be a factor, for sure," Goodell said.

San Francisco's game against Jacksonville at Wembley Stadium will be the fifth straight game Smith, a dynamic pass rusher, will miss. He entered a treatment center Sept. 23, three days after his second arrest for drunken driving since he entered the NFL in 2011.

The 49ers are planning to meet with Smith soon and are is hopeful he will return to the team this season. Coach Jim Harbaugh and general manager Trent Baalke said the reports of Smith's progress are encouraging and they want to see him make continued progress before coming back to the team.

"Certainly, the issue here isn't to discipline players. It's to stop the behavior," Goodell said. "Aldon has voluntarily said, 'I need help.'

"We're obviously there to support him, and the 49ers did a great job getting him into a facility to try to get help. We support that."

Potential scenarios are a reduced game suspension, a fine or no further discipline if Goodell is satisfied with Smith's progress and time spent away from the team.
