A reader tells us that Chargers center Nick Hardwick claimed in an appearance on XX Sports Radio 1090 that the alleged antics of Pats defensive end Richard Seymour on Sunday included applying a head butt to a member of the Chargers’ coaching staff.

We previously received an e-mail tip making that same claim, and it appeared to have been written by a Chargers player.  But we couldn’t corroborate the contention, so we left it alone.

Hardwick publicly called out Seymour after Sunday’s game, claiming that Seymour was engaged in dirty tactics.

Moments ago, we called the station to confirm that the allegation had been made by Hardwick (wow, real journalistic work), and we were told that the podcast containing the accusation will be posted within the hour.  The XX Sports Radio audio vault is right here.
