Boston Bruins centre Marc Savard has been cleared to begin participation in full-contact drills during practice.
Savard was cleared after he underwent nearly six hours of neuropsychological testing at the University of Pittsburgh Medical Center on Tuesday, according to NHL.com.
Bruins GM Peter Chiarelli said in a statement that Savard passed all tests, but "there is no timetable at this time for Marc to start playing games."
He was cleared to practise in non-contact drills last week.
The Bruins forward suffered a serious concussion March 7 when Pittsburgh Penguins winger Matt Cooke administered a violent, blindside hit.
Savard returned during Boston's second-round playoff series against the Philadelphia Flyers but struggled with post-concussion syndrome throughout the summer. He has been on injured reserve for the entire season.
Savard, who will join the team Wednesday in Florida for the morning skate, said in a statement that he felt good, but the game seemed very fast.
"The guys are fast, so I have to get used to that," Savard told the Boston Globe. "My hands feel fine. My head feels great. I'm just waiting to go. I really want to get going."
