Arrow star Stephen Amell announced on his official Twitter account that WWE and himself have collaborated to release a t-shirt promoting his match at this Sunday’s WWE SummerSlam pay-per-view. A portion of the proceeds will benefit the Emily’s House charity, a hospice for children.

The description reads, “Growing up, I loved my WWE shirts. The classic graphics with the date and arena…So if I’m going to risk life & limb in a WWE Ring this Sunday, we’re DEFINITELY doing something to raise money for charity.”
