Trevor Daley out for playoffs with broken ankle

Trevor Daley's season is over.

The unheralded defenseman will miss the remainder of the playoffs after suffering a broken ankle in a collision with Ryan Callahan in Friday's Game 4, coach Mike Sullivan confirmed after the team's workout ahead of Game 5.

Daley, the modest in-season acquisition who stepped into a major role for the Penguins, provided yeoman duty in these playoffs, logging the second-most minutes behind Kris Letang.

His most significant contribution came in what was a critical Game 4 versus the Washington Capitals in Round 2, when he scored his only goal of the playoffs in his 29 minutes filling out a lead role while Letang served a one-game suspension.

Daley will finish his tournament with the goal, plus five assists.

Olli Maatta, a scratch in six of Pittsburgh's previous eight games, took reps with Letang on the first unit, indicating he'll draw in over Derrick Pouliot.

Elsewhere, Beau Bennett received clearance to make his Stanley Cup Playoffs debut, and is expected to take Conor Sheary's spot. Sullivan, however, said that aside from the decision to start Marc-Andre Fleury, his official lineup is not yet firm.
