Non-profit organization dedicated to youth lacrosse in Livermore California.


Livermore Phantom Lacrosse Club takes player safety very seriously. We will proactively cancel/postpone practices when heat and air quality presents potential safety issues. And all of our coaches receive First Aid training including CPR and AED operation. Additionally, we have a comprehensive two-tier concussion management program: ImPACT + King-Devick.

Heat and Air Quality Guidelines for Holding Practices

With extreme heat and/or hazardous air quality possible during practices (especially fall clinics), the Phantoms have the following policies for cancelling practices out of concern for the saftey of our players and coaches

If temperatures are expected to exceed 105F during practice time, the session will be cancelled. If the temperatures are expected to reach 95-105 degrees, U10 through U14 players will limit practice to 60 minutes maximum, with plenty of breaks for water and limited use of padding. U8 practices will be cancelled.

If the air quality index (AQI) is expected to exceed 150 (unhealty), all sessions will be cancelled that day regardless of temperature. If the AQI is 100-150 (unhealthy for sensitive groups), practice will be held but activities requiring significant exertion (e.g. running, scrimmages) will be curtailed and the practice time may be shortened; players with repirator issues (e.g. asthma) should refrain from practicing. See for current conditions and forecasts as well as a description of the AQI scale.

If scheduled games are impacted during the spring season (unlikely), we will work with the other club to agree on postponement if any of the above conditions are occuring.

Phantoms will send a status update email by 8AM that morning to verify if activities are cancelled or not (or the night before if possible) and will post a news item on our website. If you do not receive a cancellation email, please proceed with scheduled activities. The club will do our best to add a make-up session, subject to field and coach availability.

ImPACT Concussion Management

Developed by clinical experts who pioneered the field, ImPACT (Immediate Post-Concussion Assessment and Cognitive Testing) is the most-widely used and most scientifically validated computerized concussion evaluation system.  ImPACT provides trained clinicians with neurocognitive assessment tools and services that have been medically accepted as state-of-the-art best practices -- as part of determining safe return to play decisions. 

All players over age 10 will receive bi-annual ImPACT baseline testing.  If a concussion is suspected, a second post-injury ImPACT test will be administered and the results analyzed by the ImPACT computer system.  Parents will be provided with a detailed report that can be used by the family's health care provider to make an informed return to play decision.

King-Devick Test

The King-Devick Test is an easy-to-administer test which is given on the sidelines of sporting events to aid in the detection of concussions in athletes. The test can help coaches objectively determine whether players should be removed from games, thereby preventing the serious consequences of repetitive concussions resulting from an athlete returning to play after a head injury.  The King-Devick test can be administered to players of all ages, thereby serving as an important compliment to ImPACT to ensure that all of our players can be evaluated.
