Alex Pietrangelo of St. Louis Blues Is Day to Day After Hit Just as they did in the first round, the St. Louis Blues dropped the series opener at home. The difference as they head into Game 2 of the Western Conference semifinals against the Los Angeles Kings is that they have an injury problem. The top defenseman Alex Pietrangelo was not at practice on Sunday, the morning after he was checked face-first into the boards by Dwight King in the Blues" 3-1 loss to Los Angeles. Although Coach Ken Hitchcock did not rule out Pietrangelo for Game 2 on Monday night, he decided on Ian Cole as a potential replacement. Cole, a first-round pick in 2007, played 26 games in the regular season and would make his playoff debut. Hitchcock, who said Pietrangelo was day to day with an upper body injury, was not interested Sunday in the debate about whether King should have received a five-minute major - instead of a two-minute boarding minor - and perhaps a suspension. "Why don't we leave that for the league?" he said.
