According to a source close to the situation, the tests were to determine whether the injury that has kept Beckham out of practice for the past week was more serious than originally believed. They determined that it was not, which is a good thing in and of itself, but it doesn't help anyone figure out when the Giants' first-round pick might return to the practice field.
The team hopes Beckham will be back in a week, but it maintains its stance that it will not put him on the field until it's certain he's not at risk of further injury. What that means is a waiting game. The Giants and Beckham will continue to monitor the hamstring on a day-by-day basis, and once it feels better to the point of allowing him to practice, he'll practice.
What that means is that Monday didn't change anything at all with regard to Beckham, who missed minicamp and has now missed five straight training camp practices with hamstring problems.
