The midfielder was sent off in the club's game against Nottingham Forest last weekend.
Daniel Pudil has admitted that losing Barry Bannan to a three-match ban is a big blow to Sheffield Wednesday's promotion hopes, but insisted that the Owls have enough quality to make up for his absence, the Sheffield Star reports.
The former Aston Villa man was sent off during the latter stages of the Owls' 3-0 victory over Nottingham Forest in their most recent Championship game so will miss the home games against Charlton and Blackburn, as well as the trip to Huddersfield in between.
And while Pudil conceded that it will be a big loss to not have Bannan available, he is convinced that the squad has the depth to cope without him.
"It is a big blow for us that Barry is out but we still have one of the best midfields in the league," he told the Star.
"We have a lot of competition with the likes of Aiden, Ross Wallace, Kieran Lee and Sam Hutchinson and it is a pleasure for me to play alongside these guys.
"I'm sure whoever will come in for Barry will play well."
Given how influential Bannan has been since moving to Hillsborough, Carlos Carvalhal will be cursing his luck that he will be unable to select him for a third of their remaining games given their current position in the table.
Wednesday may be in the top six, but know that they could be overtaken by Cardiff or Ipswich if they slip up over the weekend, while Birmingham can also keep the pressure up on them with a win in their game.
And although the Addicks are second-bottom in the table, and appear to be in disarray off the pitch, they are unbeaten in their last three games - including an impressive victory over promotion-chasing Middlesbrough in their most recent fixture - and came out on top when the two sides met in November - coincidentally, also just before an international break was about to commence.
