Full back Alan Dunne has been with Millwall since he was 10-years-old, and in recognition of his sterling service he follows Neil Harris in being awarded a testimonial.
Already plans are in place to kick-off with a golf day in October, and the year will culminate with a pre-season friendly in the summer of 2011.
Lions Player subscribers can see a full interview with Dunney on Tuesday, and there will be more news about his testimonial in the coming weeks.
