Prior to Tuesday's game at the Verizon Center against the Washington Capitals, Holmgren expanded on the situation.
"Over the last few days, his symptoms have gotten worse," Holmgren said. "He skated a little bit [Tuesday] and didn't feel that good, like himself."
The Flyers had said on Monday that Giroux was making progress. Holmgren said originally it appeared as if Giroux didn't have a concussion.
"He didn't have concussion symptoms right away," Holmgren said. "It was more whiplash and discomfort in the neck."
All that would change.
"As the last few days have transpired, it became more and more that he didn't feel like himself, was sluggish and that is the reason we are doing this," Holmgren said.
Giroux skated both Monday and Tuesday, according to Holmgren.
"I don't know if it is any good news, but after 15 minutes or so once he stopped skating [on Tuesday], he did start to feel better," Holmgren said. "But we're going to take it easy with Claude."
Holmgren said they would keep him off the ice on Wednesday and possibly revisit things on Thursday. So much has to do with how Giroux feels each day. The Flyers general manager also said that the team may have to use some tough love.
"He is a stubborn guy and wants to go out there," Holmgren said.
That will only happen when he feels like his old self, according to Holmgren.
For now, Giroux won't be seeing outside doctors the way defenseman Chris Pronger is for his concussion-like symptoms. Pronger will meet with two Pittsburgh concussion specialists on Wednesday.
"Right now we are not going to go that route," Holmgren said. "We're going to stick with our doctors. "Chris is a little different issue and Claude will stick with our doctors."
Giroux didn't undergo baseline testing on Tuesday, but he had on Monday
"He did it [Monday] and it was not bad," Holmgren said.
