The Eagles came away from the Etihad Stadium with a share of the spoils to end the weekend ninth in the table, two points ahead of opponents Southampton.
Four draws on the spin have curtailed Palace's climb up the division somewhat, but holding Arsenal and Man City in back-to-back matches is no mean feat.
The Eagles battled back to draw 1-1 with Arsenal on January 11 and came close to winning away at reigning champions City for the second season running on Saturday.
Not since West Ham in December 2015 has a team drawn five Premier League games in a row, but Palace can match that return on Tuesday should their showdown with Southampton finish all square.
Ings has been key to the Saints' recent revival, with Ralph Hasenhuttl's charges climbing away from the relegation zone and into 13th place.
Their five-match unbeaten run in the top flight was ended by Wolverhampton Wanderers last time out, however, after squandering a two-goal half-time lead to lose 3-2 on home soil.
Hasenhuttl felt a big penalty call went against his side and it remains to be seen whether the setback will have a psychological effect on Southampton, who still boast a good recent away record.
The south coast side are aiming to win a fourth consecutive away game for only the second time in their Premier League history, in fact, with 61% of their Premier League points this season coming away from St Mary's.
History is on the Saints' side, too, given that they have won four of their last six away Premier League meetings with Palace, including the last two without conceding.

Tosun is looking to become just the second Palace player after Bakary Sako to score on his first two Premier League starts for the club.
Connor Wickham has been integrated into the side in recent weeks and came off the bench against City, but Hodgson is unlikely to tinker too much on the back of the draw in Manchester.
Southampton striker Shane Long scored his first league goal of the season last time out and is expected to retain his place up top alongside Ings, who has 14 top-flight goals this term.
Yan Valery is the Saints' only confirmed absentee for the trip to South London, and Hasenhuttl has opted against rotating his side between league matches of late.
Crystal Palace possible starting lineup:
Guaita; Kelly, Tomkins, Cahill, Ward; Ayew, Kouyate, McArthur, McCarthy, Zaha; Tosun
Southampton possible starting lineup:
McCarthy; Cedric, Stephens, Bednarek, Bertrand; Armstrong, Ward-Prowse, Hojbjerg, Redmond; Long, Ings
We say: Crystal Palace 1-1 Southampton
Both teams have made themselves tough to beat over the past month, losing three of their last 17 games combined, and we expect that to be reflected in the scoreline at Selhurst Park on Tuesday.
