Take notes, Albert Haynesworth. From Jim Schwartz' s Twitter page:

Ndamukong Suh has reported, weighed-in, and passed his conditioning test with flying colors. He will be on the field for 3:15 practice.

Although Suh was not around the Allen Park area until today, he has been spending time in Nebraska working out in order to be ready to step on the field as soon as a contract was worked out and he showed up to practice. Based on what Schwartz had to say about Suh's conditioning test, I don't think there's any doubt that he was more than ready to hit the practice field this afternoon.
