Minnesota Wild forward Pierre-Marc like symptoms.
"He can speak to it better, but initially, he took a hit in Winnipeg a few weeks ago from (Jets defenseman Zach) Bogosian and from that point on, he's felt a little bit of pressure from time to time but well enough to play. He then took an elbow late in the game at Vancouver," said Wild general manager Chuck Fletcher in video posted on the Star Tribune's web site.
"The symptoms now are nowhere near as severe as they were two seasons ago. Pierre-Marc is feeling better now than he has after previous head injuries. Obviously, it's a source of concern and he'll be out indefinitely like everyone else who has these symptoms."
Bouchard was initially injured on December 13, when he absorbed a hard check from behind into the end boards by Bogosian late in a 2-1 Winnipeg victory. That collision cost the 27-year-old a pair of games, but he returned six days later.
He was hurt once again, hit by an errant elbow, on January 4 against the Canucks and did not play in a 3-1 loss at Calgary on Saturday.
The Quebec native missed more than 100 games due to the after-effects of a concussion suffered early in the 2009-10 campaign, and didn't return full-time to Minnesota until December of 2010.
Bouchard has totaled nine goals and 22 points in 37 games this season for the Wild.
