The Philadelphia Flyers announced on Monday that veteran forward Danny Briere is out indefinitely with a concussion.

The 35-year-old missed Sunday's 2-1 overtime loss against the Pittsburgh Penguins after suffering an injury during a Saturday practice session.

Briere has failed to post a goal since scoring twice on Feb. 18 versus Long Island, a 13-game drought, and has totaled only five goals and 13 points in 26 games. He endured a 23-game dry spell from January through mid-March a season ago.

Also, defenseman Nicklas Grossmann was pronounced day-to-day with his upper- body injury that caused his absence on Sunday.

This news is not promising, as the Flyers begin a crucial stretch in the postseason hunt with the first of five straight home games on Tuesday against the New York Rangers.

The Flyers rank 13th in the Eastern Conference, five points out of the final playoff spot.
