Scotland went into their opening match against new-look France at Murrayfield with high hopes of mounting a serious challenge for the championship.
But such was the dispiriting nature of the 27-6 defeat in Edinburgh that Hadden is now suddenly under the most pressure of his reign as national coach.
While an experienced pack of forwards failed to impose themselves on their youthful counterparts - with the scrum suffering in the second half and the line-out poor throughout - it was the misfiring backline which will be giving the former Edinburgh coach most food for thought.
Swashbuckling full-back Rory Lamont has already been ruled out with shoulder and ankle injuries, further depleting the Scotland coach's reserves of pace and power.
Nick de Luca endured a miserable debut at outside centre and Dan Parks - handed the number 10 shirt ahead of Chris Paterson - barely put a foot right.
However, the fact powerful centre Henderson has been cleared to play against Wales despite headbutting a French opponent on Sunday is a major relief to Hadden.
RBS 6 Nations citing commissioner Achille Reali decided no action should be taken following the incident involving Damien Traille and the RBS 6 Nations disciplinary panel felt there should be no citings from the weekend matches.
Meanwhile, lock Nathan Hines sat out training on Tuesday as nine players were added to the squad preparing for the Cardiff clash.
Hines suffered a calf injury against France. However, Scotland team doctor James Robson expects the Perpignan forward to resume training on Wednesday.
Nine players joined the 22 others on duty against Les Bleus as Hadden's squad trained indoors at Heriot Watt University's sports academy at Riccarton.
The newcomers were on duty with the Scotland A team during their 37-15 victory over their Italian counterparts on Sunday.
Glasgow Warriors trio Moray Low, Alastair Kellock and Graeme Morrison came in along with Edinburgh quartet Phil Godman, Ben Cairns, Calum MacRae and Craig Hamilton.
Gloucester flanker Alasdair Strokosch and Ulster winger Simon Danielli were also added to the training squad.
Hadden is due to name his starting line-up for the Cardiff clash on Wednesday morning.
