Dolphins coach Adam Gase said Monday that Urbik will likely miss the team's season opener due to a knee injury, Jason Lieser of The Palm Beach Post reports.
Urbik previously sat out Thursday's preseason game against the Ravens due to the back injury, but now it looks like it's his knee that is his greater concern. The Dolphins are tabbing Urbik for backup duties at center behind Mike Pouncey to begin the campaign.
