(CBS) The Blackhawks have placed defenseman Michal Rozsival on the long-term injured reserve list.

The 39-year-old Rozsival hasn’t been participating with the team in training camp and preseason games because he’s still suffering from the effects of a punch he took from Ducks forward Nick Ritchie early last April. Rozsival had surgery to address facial fractures and wasn’t clear by doctors in September as he has post-concussion symptoms, The Athletic has reported.

Rozsival had three points in 22 games for the Blackhawks last season.
