Chop blocks, eye-black shading and injury timeouts are all part of high school football. The rules that govern them have changed for 2011.

The changes in some instances will be subtle, said Marlon Harrison, president of the Baton Rouge Area Football Officials Association, but he said they will make a difference.

The definition of a chop block has been redefined. Previously, a chop block was defined as a delayed high/low contact between two linemen from opposing teams in the free blocking zone.

The rule was been expanded to include any high/low or low/high combination, regardless of whether it is deemed to be delayed or not.

High contact is considered to be at or below the waist. Low contact is at or below the knees.

The use of eye-black shading by players is now strictly defined. Players will not be allowed to wear eye black that extends beyond the eye socket. This rule will prevent players from shading their entire face, like a mask.

When injury timeouts are called, conferences between players and coaches must be conducted outside the 9-yard marks.

This change is to give athletic trainers and medical personnel more space to provide treatment.

These rule changes, along with new state laws stipulating concussion treatment protocol and setting up guidelines for comprehensive sports injury management, are all new for 2011.

Reporting games

Jamborees for volleyball and football usher in the official start of the 2011-12 high school sports year.

Louisiana School for the Deaf and Brusly High host volleyball jamborees on Tuesday, while McKinley will host its jamboree at LSD on Wednesday.

Football jamborees begin Thursday with games set at Brusly, Port Allen and Redemptorist.

The EBR/Coca-Cola Kickoff Classic set for Woodlawn High, along with BREC’s Olympia and Memorial stadiums, helps highlight Friday’s busy schedule.

The start of games also signals the time for schools to start reporting their results in these sports, along with cross country and swimming.

The Advocate sports staff has personnel dedicated to compiling high school results each weeknight, starting at 7 p.m.

Results should be submitted by 9:50 p.m. Monday through Thursday. Friday’s deadline for football is 10:45 p.m.

Any results submitted should include game scores and statistics, including first and last names for players from both teams.

Results can be called in to (225) 383-1111 or (800) 960-6397. Results also can be submitted by fax to (225) 388-0318 or by email to sports@theadvocate.com. Please call to confirm that faxes and emails were received.

Free when need be

The Football Officials Association’s Harrison said his comments about football officials doing games for free in a column I wrote earlier this week was meant to refer to emergency situations, such as a possible dispute over a pay raise.

Harrison said football officials are happy with their pay and were comfortable monitoring the LHSAA’s efforts that led to passage of pay raises in several sports.
