Mike Richards, who has been sidelined for four consecutive games with concussion-like symptoms, is unlikely to join the Los Angeles Kings for Game 5 in the Western Conference final series against the Chicago Blackhawks tonight. Facing elimination and down 3-1 in the best-of-seven series to the Hawks, the Kings would love to have their leading offensive player in the lineup but LA coach Darryl Sutter said it was "really doubtful at best" that Richards would be in the lineup for Game 5. Richards has done some light skating - the team was not on the ice Friday - and attended the Kings' last two games, in the press box for the latter. His presence at Staples Center was a positive development because often individuals suffering from severe concussion symptoms are sensitive to lights and noise and are advised to steer clear of those situations.
