Philadelphia Eagles offensive tackle Lane Johnson suffered a sprained MCL on Sunday against the Jacksonville Jaguars and could miss up to a month as a result, according to ESPN's Adam Schefter.
The 28-year-old missed 10 games in 2016 because of a suspension for violating the NFL's performance-enhancing drugs policy but played 15 contests in 2017 for the eventual champion Eagles.
Johnson, who was selected with the No. 4 overall pick in the 2013 draft by the Eagles, is one of the most important cogs in the team's offense.
