The Eagles signed Hayes to a contract Wednesday, Dave Zangaro of NBC Sports Philadelphia reports.
The undrafted rookie originally signed with the Eagles in late May but was waived a week later. Since that time, the wide receiver room has had multiple injuries. DeVonta Smith (hamstring), Makai Lemon (hamstring) and Britain Covey (hamstring) all went down with the same injury, leaving some training camp snaps open for Hayes to take advantage of.
