Speaking to the media for the first time since entering the player assistance program, Vrana cited personal reasons behind his decision to receive care.
"There's bigger things than hockey in life," Vrana said. "You're gonna deal with some things that are bigger than hockey, or whatever it may be. You have to make some decisions that are important in your life."
Vrana said he worked hard to stay in shape while away from the club.
"I've been trying to stay in shape as much as I could," Vrana said. "I felt really good out on the ice. Now, it's just a matter of time."
According to Red Wings head coach Derek Lalonde, there is no set timetable on when the Czech winger will be ready to play.
"It's just great to have him back and able to practice with us," Lalonde said. "Now, the next step is when we think he can be game-ready. Obviously, he's been out for almost two-plus months. It was his first skate today. We want to be really patient with it."
