Seabrook's first surgery will take place Friday on his right shoulder. He is also scheduled to have surgery in early January on his right hip and a third procedure on his left hip in early February.
De Haan will undergo surgery for his right shoulder Friday, the team said.
Seabrook had been termed a “healthy scratch” for the Blackhawks before last week's loss to the Colorado Avalanche, but was later observed by team physicians for an undisclosed health issue.
He was a healthy scratch for several games earlier this season. He has three goals and an assist 32 contests for the Blackhawks.
