Buccaneers Pro Bowl center Ryan Jensen feared to have suffered season-ending knee injury

It's been approximately 24 hours since Tampa Bay Buccaneers Pro Bowl center Ryan Jensen went down and was carted off the field with a left knee injury during training camp. In an update later Thursday, multiple reports said the fear was that Jensen's injury was "serious."

While there's still no definitive word on what happened to the 31-year-old, it sounds like Bucs fans should be expecting the worst.

ESPN's Jeff Darlington reported further on second-year pro Robert Hainsey, who he said should have the upper hand on the replacement gig if Jensen is done for the year.

Jensen has played and started in every game since 2017, his fourth season in the NFL, back when he was with the Baltimore Ravens.
