MILAN (AP) — Sidney Crosby left Canada’s Olympic quarterfinal game against Czechia in the second period because of injury, did not return and his status for the rest of the tournament is uncertain. Crosby’s right leg appeared to buckle when bracing for contact on a big hit from Czechia defenseman Radko Gudas a few minutes into the second. Laboring as he stayed on the ice, Crosby got crunched into the boards by Gudas and Martin Necas and then left after shaking his right leg and wincing. Crosby spoke to players at the second intermission, and Canada rallied to tie it and win in overtime.
