The Team of Choice were close to a MTN8 final berth after drawing 1-1 with SuperSport United in the first leg of their semi-final tie. However, striker Jeremy Brockie had other ideas as he netted twice in a 2-0 win for the visitors at Harry Gwala Stadium on Saturday.
Weidlich admits the defeat hurts but he is aware the Premiership leaders have little time to sulk as they will face KwaZulu-Natal neighbours AmaZulu in the league at King Zwelithini Stadium tonight (19h30).
"Of course it's hard and don't forget we were in the semi-finals. We were very close to get to the final and make history and now we are out," says Wieldlich, who took over the armband following Kurt Lentjies's off-season move to Chippa United.
"We have young players and you need some hours to recover from this disappointment. The good thing is that we're a family here. We need to recover for the game against AmaZulu today.
"I think it is important to remain focused because we have a game today. We have to keep our heads up and be ready for the league challenge."
He adds: "I believe in my teammates, I believe in the team and we know what we did wrong [against SuperSport]. I think for the next game against AmaZulu we'll be back one hundred percent.
"Last season we finished in the top eight and we are working on it. Hopefully we'll finish in the top eight like last season."
Coach Fadlu Davids is without new Cameroon signing Yazid Atouba and team doctor Gerhard van der Merwe through suspension following their dismissals against Matsatsantsa, while Kenyan defender Brian Onyango is out with a hamstring injury.
Maritzburg beat AmaZulu 2-1 in their previous meeting at Moses Mabhida Stadium on the last day of the 2014/15 season as Usuthu were demoted to the National First Division.
