It was initially reported that Giordano was going to play tonight but now looks like he won't. Still, he was taking line rushes at practice and looks close to a return.

Contrary to a previous report, Giordano (hamstring) was absent from warmups and won't play against the Bruins on Tuesday, Derek Wills of Sportsnet 960 The Fan reports.
Giordano took line rushes with the first pairing during Tuesday's game-day skate, but the veteran blueliner will take another night off before suiting up for his first game since Feb. 4. Michael Stone will draw into the lineup in Giordano's place.
