The Owls' top goalscorer was sent off for the second time in two Championship games when he was dismissed against Hull on Friday.
Carlos Carvalhal has insisted that Sheffield Wednesday will be able to win their next two games despite the fact that they will not be able to call upon Fernando Forestieri, the Sheffield Star reports.
The former Watford man received a highly controversial red card during the Owls' goalless draw with Hull City on Friday, and will now serve a two-match ban having been dismissed in his previous appearance, so will miss the home clash against Rotherham and the trip to Brighton.
And while some Wednesday supporters may be concerned about what impact Forestieri's absence will have on their next two results, Carvalhal has pointed out that his side have had a number of key players missing over the course of the season, and having come through those periods largely unscathed, they should be able to continue their promotion push without the forward.
"Of course, we prefer to play with all the players and Fernando's a special player to us," he told the Star.
"We have won without the likes of Barry Bannan, Gary Hooper and Keiren Westwood this season so we can win without Fernando."
Although the Portuguese is confident that his squad have the ability to cope without Forestieri, there is no question that they could have done with having the 26-year-old available for their upcoming fixtures.
The Italian is the Owls' top goalscorer in the Championship, so may be one of the men that Carvalhal was relying on to help the side get back to winning ways. Wednesday have won just twice in their last eight games in all competitions, and have not won in their last three games.
And while they will still be confident of beating Rotherham, the encounter with the Seagulls presents a much tougher challenge. Chris Hughton's men have won their last two games 4-0 and sit eight points clear of Wednesday in the table.
