''Hopefully they can find out why, when I was hit flush on the head, it split the skin through the helmet and I needed stitches,'' Langer was quoted by the Australian as saying.
''I was so severely concussed that I think it is important they have a look at it. I missed basically three Tests as a result,'' the Aussie added.
The prolific opener's 100th Test party came to bloody end on the opening day of the third Test against Proteas in April when he was hit by the first ball of the first innings.
Langer is still waiting for reports on any long-term damage that may have been caused by the blow and complained of chronic headache for two days following the incident.
''I have been hit a few times before. Obviously it hit me absolutely in the wrong spot,'' he said adding, ''To be concussed through the helmet is a bit of an issue, for sure.'' The 35-year-old also talked to the manufacturers of the helmet.
''We did discuss a few things, a few options, he was very good,'' helmet manufacturer Albion's sales and marketing manager Ross Barrat said adding, ''What we are trying to do is get back as much feedback as we can from JL. I physically haven't seen the helmet in question.
We have got to take it from there.'' The Test star, who has stopped fielding at the short leg on doctors' advice after being hit several times, has taken atleast seven blows while batting.
