Boston Bruins centre Marc Savard is having "real memory problems and is quite worried about it," a source told ESPN.com on Saturday.
Savard suffered his second concussion in less than a year when he was hit into the boards by Colorado's Matt Hunwick on January 22nd and has been placed on his team's long-term injured reserve.
Savard scored two goals and eight assists in 25 games after returning to the ice, albeit briefly, this season. Savard sustained his first concussion on March 7, 2010 after a check by Pittsburgh Penguins forward Matt Cooke and did not return until the second round of the playoffs last season.
He also missed the first 23 games of this season.
Cooke is currently under suspension for his more recent illegal hit on New York Rangers defenseman Ryan McDonagh. The recent league-wide upswing in head shots led the NHL to outlaw blindside hits to the head.
Savard said he has also suffered from bouts of extreme drowsiness and also said things seem to move slower since he sustained his injuries.
