But just before the break, Rakshi was sent crashing to the floor in the area, Lloyd tucking away the spot kick off a post.
In the second half, Kershaw produced another stunning save and then had a hand in the next goal as his long clearance found Lloyd, whose shot was parried, and Rakshi reacted first to slam the ball home. However, Enfield equalised immediately, as a ball into the box was hooked in.
