Peters and Johnson have combined for 10 Pro Bowl appearances.
Peters left the game with a head injury, while Johnson suffered an injured leg. Johnson was carted off the field and taken to the locker room. Johnson was declared out for the game in the second half.
Three-year veteran Halapoulivaati Vaitai replaced Peters at left tackle, while Isaac Seumalo entered the game in place of Johnson. Vaitai does have significant experience at left tackle, though, replacing Peters in Oct. 2017 following an ACL tear to the nine-time Pro Bowler.
Philadelphia's offense found its footing to close the first half despite the injuries, reaching the end zone on a Dallas Goedert touchdown catch late in the second quarter. The Eagles lead the Jaguars 10-6 at halftime at Wembley Stadium in London.
