Linebacker John Timu made the Bears' opening day roster as an undrafted rookie and played in the first four games of the season on special teams.
But Timu was then waived and signed to the practice squad, where he spent 10 weeks before being promoted back onto the active roster Tuesday. Like so many others who transition from college star to the NFL roster bubble, it's been an adjustment for Timu.
"It's rough, but it comes with the territory in this business," he said.
