Landon Dickerson exits Eagles game vs. Steelers with a knee injury

Philadelphia Pro Bowl left guard Landon Dickerson exits the Eagles game vs. the Pittsburgh Steelers with a knee injury

The Eagles have one of the NFL’s deepest offensive lines, and that depth will be tested if Landon Dickerson doesn’t return in Week 15.

Philadelphia’s Pro Bowl left guard exited midway through the third quarter with what the team described as a knee injury.

Dickerson’s return is questionable, so Tyler Steen was inserted into the lineup at left guard, with Mekhi Becton starting at right guard.

According to PFF, Dickerson is the 13th highest-graded offensive guard in the NFL (80.2), and his 80.4 run block grade is 11th in the league.
