Eagles DE Jason Babin is expected to miss 2-3 weeks with a calf injury, Reuben Frank of CSNPhilly.com reported Tuesday.
The injury is a second-degree strain, according to Frank.
The 32-year-old Babin notched a career-high 18 sacks in 2011. He has emerged as one of the NFL's better pass-rush threats in the last two seasons.
The Eagles begin the regluar season at Cleveland on Sept. 9.
