Concussions to then-Eagles Kevin Kolb and Stewart Bradley within minutes in the 2010 season opener were shown on video  to NFL officials Tuesday as an instructional aid.

Unfortunately the officials have been locked out by the owners, who are reluctant to give them a contract on anything but their own terms.

Veteran Eagles want the veteran officials reffing the games. Brent Celek told me the familiarity is huge on game day. Players know how officials officiate, and officials understand the way players play.
