Grown men fighting over pee-wee football? That’s strange enough.

What makes the story more interesting, however, is that it involved a current Alameda County supervisor and a former Oakland Raiders player.

Sometimes, you can’t make this stuff up.

According to San Francisco Chronicle columnists Matier & Ross, Supervisor Scott Haggerty and former NFL tight end Jeremy Brigham are under investigation by Pleasanton police for an altercation that put Haggerty in a neck brace.

Apparently, Haggerty had recently been fired as Brigham’s assistant coach of the 10- and 11-year-old squad and was leaking plays to an opposing team. Now this is serious stuff.

Police Sgt. Jim Knox confirmed that his department is investigating the incident, according to the columnists.

More juice from the column:

“Haggerty said his advice to head coach Brigham wasn’t always welcome, and that Brigham told him to “shut up and sit down” after he complained about the team’s exercise regimen and asked to take over. ….

At a coaches meeting the next day, according to Haggerty, the losing coach walked up to Brigham and joked, “Haggerty gave me all your plays.”

That Monday, when Haggerty showed up at the Foothill High School football field to pick up his son from practice, Brigham confronted him, “screaming that I gave the plays away,” Haggerty told us.

The next thing he knew, Haggerty said, Brigham had knocked his BlackBerry from his hand and was pulling him over a 4-foot fence as he punched him on the back of the head.

The hidden gem in this story is a quote from Mike Shevelson, vice president of the Pleasanton Junior Football League, who said that “it’s an internal thing for the league” and “you’re doing a disservice to report it” to the columnists.
