The Owls won three consecutive games in the Championship while the midfielder was out.
The midfielder's red card was the only low-point from a fantastic 3-0 win away to Nottingham Forest in March and meant that he had to sit out the games against Charlton, Huddersfield and Blackburn.
But after Carlos Carvalhal's men picked up maximum points from the fixtures - which included another 3-0 win, against the Addicks - Bannan admitted that their form made watching from the sidelines much easier.
"It felt like I was out for ages with the international break," he told the Star.
"I missed three games but we luckily won them all. The boys were brilliant so that made it a bit easier."
Worryingly for the 26-year-old, his return to the side coincided with a surprise 4-1 defeat away to Bristol City, who had spent much of the campaign battling near the bottom three.
Nevertheless, the contribution that the former Aston Villa man has made since moving to Hillsborough will ensure that Carvalhal does not put too much emphasis on Bannan's return coming in the same game as the one that saw Wednesday's four-match winning run come to an abrupt end.
In fact, it will surely be the likes of Bannan that the Portuguese will turn to to ensure that the Owls get their promotion push back on track against Ipswich.
