The status of Blues forward David Backes remains uncertain a day after he was knocked out of Game 2 on an illegal hit by Chicago's Brent Seabrook. The club held an optional practice Sunday, of which Backes obviously did not take part, and afterwards head coach Ken Hitchcock was asked about the captain's condition. "All I know is he's upright...that's about it right now," Hitchcock said. "We don't have any further information and probably won't until late tomorrow." Hitchcock was then asked if he believed that Backes had any chance of playing in Game 3 against the Blackhawks Monday night at the United Center. "I have no idea ... I have no idea right now," Hitchcock said. "I know one thing: he couldn't play today." The NHL's Department of Player Safety held a phone hearing with Seabrook Sunday at 11 a.m. St. Louis time and announced shortly before 2 p.m. that it had suspended the defenseman for three games. Seabrook will sit out Games 3-4 and Game 5 if it's necessary. The Blues have a two games to none lead in the best-of-seven series. In addition to Seabrook's hit, the Blues were disgusted by on-ice comments made by Chicago defensemen Duncan Keith, while Backes still lay motionless. On audio heard via the CBC television feed, Keith is heard saying "Wakey, wakey" to Backes — a reference to the captain being potentially knocked out by the hit.
