Carson Wentz revealed he tore his LCL while also tearing his ACL in December.
Wentz does not anticipate the additional damage will significantly impact his length of rehab.
Wentz is aiming to return for the start of the 2018 season.
"My goal is to be out there Week 1. The timetable stuff, I wish I knew just as much as you guys wish you knew," he said Friday. "It's just such a fluid process, and we'll just see what happens."
