Owens missed practice for a second straight day with lower back spasms and the team sent him for the test as a precaution. The MRI came back negative.
Earlier in the day, Dallas Coach Wade Phillips said he felt there was no reason for alarm. "He wants to play," said Phillips during his news conference after morning practice. "I thought he'd be a little better today ... but it wasn't better. It was a precaution."
Owens also missed practice Sunday with the back injury. He missed three practices early last week to rest his legs. His status for Thursday's preseason opener against Indianapolis is uncertain.
In his first season with the Cowboys a year ago, Owens had 85 catches for 1,180 yards and 13 touchdowns.
