The team said Peverley was released from St. Paul University Hospital in Dallas on Wednesday night. He was with the team during practice Thursday at headquarters in suburban Frisco.
Peverley is out for the season and will soon go to Cleveland for a procedure to fix an irregular heartbeat that was diagnosed in training camp. He collapsed during the first period Monday night against Columbus. The game was postponed.
The 31-year-old decided not to have the procedure after the diagnosis. He chose a less invasive adjustment and medication.
Peverley missed a game last week when he didn't feel well.
