basic cylinder with capsule collider

I just imported a maya file with a standard cylinder. I gave it a RigidBody and Capsule Collider.. set it just above the terrain. When the cylinder "collides" with the terrain, it falls over like a drunk cylinder and then rolls down the terrain. How can I keep this thing standing up? (it's supposed to represent my player).

Use "No Rotation" on the rigidbody component :)

Hope this helps
