PHILADELPHIA -- Eagles right tackle Lane Johnson is recovering from ankle surgery he had in August, according to league sources, another twist in a saga-filled couple of months for Philadelphia's offensive line.
The surgery was described as a "clean up" by a source.
Johnson, one of the best right tackles in the game, is considered day-to-day and his availability for Sunday's opener at Washington will be determined later in the week, according to coach Doug Pederson.
Johnson returned to the practice field in a limited capacity this week after missing the bulk of training camp with the injury.
He suffered a high ankle sprain last December and missed the final three games of the regular season and the wild-card playoff loss to the Seattle Seahawks.
It has been a rough summer for the Eagles' offensive line. They lost two of their projected starters in standout right guard Brandon Brooks and left tackle Andre Dillard to long-term injuries. Jason Peters was brought in to replace Brooks at guard but has since moved back to Carson Wentz's blind side, receiving a pay raise after doing so.
