Better late than never.

McDonald’s is kicking off December by officially entering into the so-called "Chicken Wars" — a food fight that Popeyes started in August with the initial release of its now-infamous Chicken Sandwich — with a brand-new "Crispy Chicken Sandwich" that shares several of the same attributes.

The fast-food chain announced the new chicken sandwich on Twitter, confirming that it will be available as part of a test in two U.S. cities starting Monday.

The tweet included a photo of a McDonald’s branded bag and had a photo of a chicken silhouette with “12/2” printed in it, along with the two cities.

“Houston. Knoxville. Lunch tomorrow? No beef,” the chain shared on Sunday, Dec. 1, along with an emoji of a chicken's head and a winking face.

The tweet included a photo of a McDonald’s-branded bag featuring a graphic of a chicken's silhouette containing the date “12/2." The bag itself also listed the names of both cities where the tests would be taking place.

The Crispy Chicken Sandwich appears to be a dressed-down version of the chain's other chicken sandwich options, as it features a fried chicken filet served on a potato roll, topped with butter and pickles. The deluxe version will include tomatoes, lettuce and mayo. (McDonald's currently offers a Buttermilk Crispy Chicken Sandwich and a McChicken.)

Similarly, Popeyes’ Chicken Sandwich and Chick-fil-A’s original Chicken Sandwich are both served with fried chicken filets, sauce — or butter, in Chick-fil-A's case — and pickles.

McDonald’s is even doubling down on its efforts to overtake Popeyes and Chick-fil-A in the chicken sandwich wars by serving its new sandwich in a bag, just like its competitors.
