Carolina Panthers left tackle Matt Kalil underwent a scope to clean up his right knee and is week-to-week, the team announced Tuesday.
"Matt Kalil traveled to Florida on Monday to receive a second opinion on his right knee from Dr. James Andrews," team trainer Ryan Vermillion said in a statement. "After consulting with Dr. Andrews, the decision was made to perform an arthroscopic procedure on Matt's knee. He will be evaluated on a weekly basis."
Kalil had been dealing with a sore knee that kept him out of practice.
For a Panthers team that has suffered terrible injury luck to its offensive line this summer, the news on Kalil could be worse. Even if he can't make it back for Week 1, the injury shouldn't keep Cam Newton's blind-side protector out long.
