Mathieu Perreault is back on the ice for Capitals’ practice after he was speared by his own stick in a collision with Buffalo’s Christian Ehrhoff.

Perreault was sent to a Buffalo area hospital for evaluation following the Capitals’ 4-2 loss to the Sabres on Monday night and he did not return to Washington with the team. The 23-year-old center was on an early flight back Tuesday morning, though, and is taking part in practice as usual with the rest of the fourth line.

A few other quick notes from Tuesday’s practice at KCI:

--Mike Green is taking part in practice and was not on the ice prior to the session for the main group. He is rotating through most drills and has remained on the ice for the opening 20 minutes of practice.

--New day and new lines are on the ice including a reunion of the big three of Alex Ovechkin, Nicklas Backstrom and Alexander Semin as the top unit.

The lines:

--Defensive pairings remain the same as they were Monday night in Buffalo with John Erskine and Jeff Schultz alternating working alongside Dmitry Orlov.


--Not sure when we might see them in a game, but Tomas Vokoun is sporting new pads in practice. They’re the same style as his previous ones but with the reversed coloring. The new ones have a red backgrounds with the large white diamond shape on the front.
