Covey (hamstring) did not participate in Wednesday's training camp session, Tim McManus of ESPN.com reports.
It is unclear when Covey suffered the hamstring issue, but it was likely during Tuesday's session. The 29-year-old joins fellow wide receivers DeVonta Smith (hamstring) and rookie Makai Lemon (hamstring) in dealing with the same issue. In response to the apparent hamstring injury bug sweeping the room, the Eagles signed Brandon Hayes to fill in at receiver.
