The game will match the league's All Stars against an international club that's yet to be named.
"Colorado has become a destination for marquee soccer events, and we are thrilled to bring the AT&T All-Star Game to the region," MLS Commissioner Don Garber said in a statement.
This year will be the 12th time that the MLS All-Stars have played an international team. The MLS clubs have an 8-3-1 record in that span, including a 2-1 win last year against Germany's FC
This will be the second time that the Rapids have hosted the game. The first was in 2007, when the MLS All-Stars defeated Celtic FC of Scotland, 2-0.
