The visitors progressed through their group in first place, while their hosts find themselves in South America's secondary competition after dropping out of the Copa Libertadores.
Match preview
After triumphing in the final of Clausura phase of last season's Categoria Primera A, Deportivo Cali booked themselves a place in the Copa Libertadores group stage, and they began in positive fashion with a 2-0 win over Argentinian giants Boca Juniors.
A defeat and a stalemate with Corinthians, either side of a draw against Always Ready, did harm the Colombian side's hopes of advancing to the knockout stage, but they retook second spot with a win in the reverse fixture in the latter, as Jhon Vasquez hit a brace alongside a Santiago Mosquera goal in a 3-0 thrashing on home turf.
That left them leading Corinthians in the top two on goal difference heading into the final round of fixtures, but, with the Brazilians getting a draw, a narrow defeat to Boca Juniors denied Rafael Dudamel's side a place in the final 16, as they were unable to bounce back and level the game after Alan Varela's 54th-minute opener.
With their domestic campaign also on hold after a disappointing 19th-placed Apertura finish, Los Verdiblancos will aim to reignite their season with a win to move closer to reaching the quarter-finals.
They take on a Meglar side who excelled in the Copa Sudamericana group stage, after battling through a qualifying tie.
A fifth-placed aggregate finish in the 2021 Peruvian top flight saw the visitors just miss out on Copa Libertadores qualifying and instead booked a meeting with Ciencano for a place in the Copa Sudamericana group stage, and they advanced with a 2-1 win over two legs.
Their group campaign did not get off to a good start, as they suffered an opening 2-0 defeat to Cuiaba, before rebounding with a double over River Plate and a win over Racing Club to move into the ascendancy.
A 1-0 defeat to the latter saw them fall three points behind them going into the final round of fixtures, with their round-of-16 place in peril as a result, but Nestor Lorenzo's side successfully leapfrogged the Argentinians, who suffered a defeat, with a 2-1 win over Cuiaba thanks to a late brace from Cristian Bordacahar.
Now on the back of an important 1-0 victory against Atletico Grau to remain at the summit of the Peruvian Primera Division Apertura table, El Domino will go in search of a positive result away from home before welcoming Deportivo Cali in the reverse leg.
