Reid did not specify where on the scale (grades I, II or III) of MCL injuries Celek's falls in, but that it's considered "mild" and that there are no plans to bring in reinforcements indicates that it's a Grade I tear, which usually sidelines an athlete for a week or two. The Eagles do not open the preseason for another 13 days, which means Clay Harbor, Brett Brackett and Chase Ford will benefit from additional reps during practice while Celek rests.
Adding a tight end was a consideration earlier this week when the Eagles hosted Visanthe Shiancoe. The 32-year-old ended up signing a one-year contract worth up to $2 million with the New England Patriots. At the same time, multiple reports indicated that the Eagles were set to host the 31-year-old Shockey, but that visit was put on hold.
