When Joe Sakic left after the first period in Saturday's preseason game against the Los Angeles Kings in Las Vegas, Avalanche management quickly made their way to the dressing room to learn more. Sakic suffered an injury, but Sunday the Avalanche listed it as nothing more than a minor hip flexor. The Colorado captain isn't expected to miss much time. Sakic may have been shaken up on a check along the boards by Kings forward Sean Avery in the first period, or the slushy ice of the MGM Grand Garden Arena could have played a part. The Avs did not disclose specifics of how the injury occurred.
