There were real concerns about Lambert the last few weeks concerning his academic situation. He had to graduate from GMC to be eligible this spring and I don't know for certain whether or not he graduated as he just finished up school in the last few days.
If he did not graduate he would just have to graduate before the summer to get in to a school and he would be eligible for the fall.
If he didn't graduate his NLI would be void. I'm not sure if Tennessee would want him. I would assume he would because I still he think he could help them, but I don't know for sure.
