"Center Dave Bolland will not be in the lineup for the Chicago Blackhawks when they face the Washington Capitals on Sunday at Verizon Center.

Bolland suffered a concussion during the first period of the Hawks' game against the Lightning on Wednesday night when he took a flagrant elbow from Tampa Bay's Pavel Kubina, who was suspended three games for the hit.

"We'll say (Bolland's) day-to-day but it's tough to forecast," Hawks coach Joel Quenneville said following Saturday's practice. "We're seeing a little progress."

Michael Frolik is expected to shift from wing to center on a line with Bryan Bickell and Marian Hossa."
