Philadelphia Eagles right tackle Lane Johnson suffered an MCL sprain in Sunday's win over the Jacksonville Jaguars in London, NFL Network's Mike Garafolo reports.
Johnson could miss about a month with the injury, ESPN's Adam Schefter reports, though he'll be aided by the team's upcoming bye week.
The 28-year-old needed to be carted off the field in the first quarter, and was replaced by Halapoulivaati Vaitai.
The loss of Johnson comes at a time when left tackle Jason Peters is also banged up. The veteran was dealing with a biceps injury coming into Week 8, and also briefly left Sunday's game with a head injury.
