Cowboys’ Williams hit helmet-to-helmet

Cowboys wide receiver Roy Williams was hit helmet-to-helmet by

Packers safety Nick Collins midway through the third quarter.

Williams was able to get up and run off the field on his own

power and returned to the game later in the drive.

Jon Kitna threw a deep ball to Williams, whose back was turned

to Collins when the safety came in and made contact with the back

of Williams’ head with his helmet. Collins was flagged for

unnecessary roughness.

Williams crumpled to the ground face first near the Packers’

sideline while Aaron Rodgers and other Packers players hurriedly

called for the Cowboys trainers.

After Williams’ helmet was taken off, he got up and jogged off

the field without assistance. The league is closely monitoring

helmet-to-helmet hits, saying they can result in suspension.
