PHILADELPHIA -- Dodgers reliever Ronald Belisario was activated from the restricted list Tuesday, but would not tell reporters why he went on it.

"No, I can't talk about it," he said.

Instead, he issued this statement through the club:

"I was placed on the restricted list to deal with certain personal issues. At this time, those issues have thankfully been resolved, and I am ready to join my teammates. Given the personal nature of my issues, I cannot comment any further. I am looking forward, not backwards."

The Los Angeles Times has reported that Belisario was undergoing substance abuse treatment. Belisario, who was arrested on a DUI charge last summer, would not confirm or deny it.

"I don't want to talk about it," he said. "It is resolved."

Belisario said he did not think the cause of his recent absence would mean a repeat of this past Spring Training, when he reported five weeks late because of visa problems tied to his arrest and began the season on the restricted list. He also was late to Spring Training the previous year.

He said he believes that he will remain with the club for the rest of the season.

Belisario said he continued to work out while he was gone, the first two weeks at a location he would not disclose, two weeks following that at Dodger Stadium. He went on a two-game rehab assignment Saturday and Sunday, pitching one inning each day for Class A Inland Empire.

"I feel pretty good," he said. "Two innings, ready to go."

He said he did not feel compelled to address his teammates but he did regret leaving in the middle of the season, which created a hole in the bullpen and resulted in the acquisition of Pittsburgh closer Octavio Dotel.

"You know what, I feel like things happen for a reason," he said. "I don't have to worry about it, just keep going forward. That's the only thing right now."

Manager Joe Torre said he has enough confidence to use Belisario in "significant" situations, but there's enough bullpen depth now that it won't be in game-saving situations.

"With the help we have at the end of the game, he won't be a long reliever, but the sixth or seventh inning, something significant," Torre said. "We have a number of guys who can pitch in the eighth -- the seventh and he'll be in that group -- but I don't see him in the eighth or ninth initially. He had only two rehab games. The only question right now is command, getting the ball down."

Torre said there was no need for Belisario to address his teammates.

"I don't think the team felt he deserted them," Torre said. "It was more concern when he left. There was no anger."
