eek.Villa confirmed in a statement on Tuesday that assistant boss Culverhouse and head of football operations Karsa had been suspended ''pending an internal investigation'', with Gordon Cowans and goalkeeper Shay Given being temporarily promoted to assist Lambert and his first-team coaching staff.
On Villa's official website on Wednesday, Lerner said Lambert had shown "total loyalty and commitment" to the club in his handling of "some unexpected issues", but neither Culverhouse nor Karsa were mentioned by name.
Lerner said on avfc.co.uk: "Our manager has been faced with some unexpected issues that could have very easily set the club back.
"In watching him handle matters, along with our chief executive (Paul Faulkner), I've seen total loyalty and commitment to Aston Villa while Gordon, a Villa man through and through, has repeatedly stepped up to support the club regardless of the ask.
"Shay, too, has been unhesitating in answering the manager's call.
"I couldn't ask for more from people who are up for this challenge and the very real obstacles we have to overcome, as is everyone at the club."
The suspensions, which are thought to be of a disciplinary nature rather than being directly related to Villa's recent performances, have come at a difficult time for the midlands outfit, who have lost four matches on the bounce and are still threatened by the prospect of relegation from the Barclays Premier League.
In a statement issued on Monday, Faulkner admitted all staff at the club were ''hurting'' and called for the Villa fans to get behind the team, with everyone "pulling together".
In Tuesday's announcement, Lambert was only quoted as expressing his delight at having Cowans and Given to assist him and stressing that "the whole group" are focused on Saturday's home clash with Southampton.
Cowans, who served previously as first team coach and won the European Cup as a Villa player, said: "When the manager asked me to step up I didn't hesitate
This is a challenge we face and we face it together as a club.
"From now until the end of the season we need 100 per cent commitment from everybody and I know we'll get this."
Given, the holder of a UEFA A License, said: "The players are desperate to succeed here and to secure the results we need between now and the end of the season.
"There's real belief, too, which has always been there.
"Any club can go through trying periods but the most important thing for me is the football club
The football club will always be here and that's why it's the most important thing, so we all know our responsibilities.
"We all know that we can get the results we're looking for and I had no doubts in my mind whatsoever the moment the manager asked me to step up."
Villa are four points clear of the relegation zone with five games left to play this term.
