The winger has informed the Detroit Free Press that he still suffers from occasional headaches.
"It's been miserable," Eaves said. "It's just no fun. I'm just worried about getting better every day. That's all I can do."
However, Eaves remains optimistic he will be back on the ice this upcoming season.
"(The) bad part is behind me now. This is part of the progress, skating with other guys and trying to get used to that. The speed is, obviously, not what it is at training camp. I'm just happy to be out there with the guys," he added.
Eaves is well aware of the severe consequences concussions can have on the human body. While several players in the NHL -- such as Philadelphia Flyers defenseman Chris Pronger, Pittsburgh Penguins captain Sidney Crosby, St. Louis Blue forward David Perron and Florida Panthers forward Peter Mueller -- have dealt with concussion symptoms, Eaves' father Mike is a former NHL player and the head coach of Wisconsin's hockey team who experienced the impact of a significant head injury.
"He had to end his career because of a concussion," Eaves said. "He's been a really good sounding board. When he had his concussions, there wasn't all this research out. It's a lot different now from the late '80s, when he went through it. Doctors nowadays are so much more informed. I think it's really good what they're doing right now."
Eaves, who is looking forward to skating every day, posted one assist in just 10 games last season.
