If the Eagles hope to defend their title, it won't come without a healthy amount of obstacles.
The latest is a knee injury to right tackle Lane Johnson. An MRI confirmed Johnson has a grade 2 MCL sprain and will miss several weeks, NFL Network Insider Ian Rapoport reported.
Johnson's absence will be the latest change along the offensive line for the Eagles, who replaced veteran guard Stefen Wisniewski with the younger Isaac Seumalo earlier in the season. Philadelphia has also tossed in last year's key replacement, Halapolivaati Vaitai, in occasional instances at either left tackle and/or as a sixth lineman.
Johnson's loss, however, is much larger than a willing substitution. The Eagles haven't had a horrible go of protecting Carson Wentz, ranking in the top 10 of Pro Football Focus' team pass protection rankings, but they'll miss Johnson.
