De'Vante Harris and one guy on the practice squad. Either they're downplaying the injury or Crawley got really lucky because a dislocated knee cap is just about the worst injury possible (see Teddy Bridgewater.)

Well it really depends on if the ligaments and tendons gets injured in the process. I had a friend that dislocated her kneecap, she just "plopped" it back into place and was fine with just minor swelling, others pretty much destroy their knee with such an injury so there is quite the span.
