Paille on practice ice with B's

DETROIT -- The Boston Bruins held an optional practice Wednesday at Joe Louis Arena, and forward Daniel Paille (head) was on the ice, wearing a green no-contract sweater.

He has not played since suffering the head injury on April 12 against the Buffalo Sabres at TD Garden. He has been skating for nearly a week on his own, but there’s still no timetable on a possible return to game action.

“He hasn’t been cleared, to my knowledge,” said Bruins coach Claude Julien. “He can skate right now and he’s following protocol.”

With Paille sidelined, forward Jordan Caron has been playing on the Bruins’ energy line, along with Shawn Thornton and Gregory Campbell. Caron notched his first Stanley Cup playoff goal during Boston’s 3-0 win over the Red Wings in Game 3 Tuesday night.
