Hincapie has played just once for Arsenal after joining them on loan from Bayer Leverkusen in the summer.
The defender trained again on Monday afternoon, though, and will hope to be in the squad on Tuesday against Atletico.
Ben White and Myles Lewis-Skelly could come into the team at full-back, while Mikel Merino is an option in midfield.
The most likely change is Gabriel Martinelli coming in on the left flank, although Leandro Trossard did score the winner at the weekend at Craven Cottage.
Arsenal are looking to maintain their perfect start to the Champions League this season after beating Athletic Club and Olympiacos.
Viktor Gyokeres is set to lead the line again and he will be looking to end his goal drought. The striker has not scored in his last nine games for club and country.
**Arsenal predicted XI (4-3-3):** Raya; Timber, Saliba, Gabriel, Calafiori; Eze, Zubimendi, Rice; Saka, Gyokeres, Martinelli
**Injured:** Jesus (knee), Havertz (knee), Madueke (knee), Odegaard (knee)
**Time and date:** 2pm BST on Sunday, October 26th, 2025
