The Philadelphia Eagles will be without Lane Johnson for the first four games of the 2014 season after testing positive for performance-enhancing drugs.

Johnson missed just one snap in 17 games last season as a rookie right tackle.

The Eagles’ first four games are against Jacksonville (home), Indianapolis (away), Washington (home) and San Francisco (away).

The Eagles’ two best options as far as replacing Johnson for those first four games would be moving right guard Todd Herremans back out to right tackle, where he played eight games in 2012 before suffering a season-ending foot injury.
