The Vikings' starting cornerbacks, Cedric Griffin and Antoine Winfield, both sat out on Saturday, allowing Chris Cook and Asher Allen to continue their battle for the nickel cornerback position.
Allen and Cook both had their share of miscues.
Cook got caught with his eyes in the backfield when Jake Locker dropped a snap, leaving Titans' receiver Yamon Figurs wide open for a 45-yard touchdown. Cook also missed a few tackles.
Allen missed an open-field tackle on a screen play, and the next play he let a receiver get behind him for a long pass down the sideline.
Rookie Brandon Burton looked pretty good in coverage, but had trouble locating the ball in the air.
Tyrell Johnson and Jamarca Sanford, who are competing for a starting safety position, both saw plenty of playing time against the Titans. However, neither player made a strong case to win the job.
The Vikings secondary failed to impress during the preseason opener, granted they were without their two studs. There were too many missed tackles and blown assignments to be pleased with the performance.
