Tampa Bay Buccaneers Pro Bowl center Ryan Jensen will undergo an MRI after injuring his left knee during practice.
In a concerning development for an offensive line that already has some question marks along the interior, Jensen was injured during a team drill during Tampa Bay's second day of training camp.
The normally durable eight-year veteran was carted off while unable to bear weight on his lower left leg and was replaced by second-year player Robert Hainsey.
"We'll wait to find out what it is and we're hoping for the best," Buccaneers general manager Jason Licht told reporters while adding that testing results may not be known for a few days.
Jensen has not missed a game since signing with Tampa Bay in 2018 following a four-year stint with the Baltimore Ravens and was named to his first career Pro Bowl last season.
The 31-year-old re-signed with the Bucs in March on a three-year, $39million contract that includes $23m in guarantees.
Licht acknowledged that Jensen's injury had dented the positive tone at a camp that began with great optimism. That positive mood had been further enhanced by this week's signing of seven-time Pro Bowl receiver Julio Jones as well as tight end Kyle Rudolph.
"That usually happens when you have a player like Ryan who is obviously a very good player, but also just a great person and a leader, and his toughness, things like that, about him that define him," Licht stated.
"When a player like that gets hurt and he's played through several injuries in his career, without missing any time, it deflates everybody."
The Buccaneers are already breaking in new starters at both guard spots following the offseason retirement of Ali Marpet and the departure of Alex Cappa, who signed with the Cincinnati Bengals as a free agent.
Licht was able to fill Cappa's right guard spot by acquiring Shaq Mason in a trade with the New England Patriots. Hainsey, a third-round pick in 2021, was competing with veteran Aaron Stinnie and rookie second-round pick Luke Goedeke for the starting job at left guard.
