The Pittsburgh Penguins' defensive depth will be tested yet again.
Brian Dumoulin will miss four-to-six weeks after undergoing surgery for a broken jaw, the club announced Wednesday.
Dumoulin was hit by an errant shot during Tuesday's win over New Jersey.
He joins Kris Letang (lower body), Trevor Daley (upper body), and Olli Maatta (illness) on the Penguins' injured list, with Justin Schultz and Ian Cole left to lead the charge.
