Would i be eligible to play tennis in grad school?

I am a 2010 college graduate with a bachelor degree. The initial job hunt is not going well due to the economy and i am reconsidering going back to grad school to pursue my masters. My question is regarding my ability to participate in tennis as a grad student. Is this possible? in 2007 and 2008 i played NJCAA tennis. I was planning on going on to play tennis at the next level, but due to the lack of schools offering my degree and tennis, i choose to focus on my academics and leave tennis behind for a while.So now im wondering if its possible for a grad student who played njcaa tennis to join a ncaa team?
