I haven't seen anything on here about how Shakir did in the combine. Check out the speed. I think he surprised quite a few "experts" with his time (even though this ended up being unofficial). His official time was later posted as 4.43, which is still pretty bw fast.

In an extended video on nfl.com, you can hear them say they think he pulled something at the end. I couldn't find anything else about that. Hopefully, he is all right.
