Abstract: A size adjustable soccer goal. A frame has corners and includes tubular members replaceably attached to each other allowing the frame to be size adjustable and knockdownable. A net operatively and replaceably attaches to the frame allowing the net to be size adjustable to accommodate a size of the frame and be removable from the frame. The corners of the frame are one-piece with associated members of the frame, respectively, eliminating small separate additional corner pieces from getting lost, requiring additional assembly, and compromising structural integrity of the frame.
