Seattle Seahawks backup quarterback Drew Lock was wheeling and dealing against the Dallas Cowboys, but his night ended a little earlier than expected when he took a low hit from Sam Williams late in the 2nd quarter. Williams was assessed a roughing the passer penalty on the play, but Lock stayed in and Seattle eventually scored a touchdown.
After the drive, Lock was taken into the blue medical tent to get checked out, and was replaced by Holton Ahlers for the rest of the evening.
Post-game updates from both Pete Carroll and Lock himself indicate that he avoided something catastrophic.
