Australia's Chris Rogers feared for career at Lord's

He missed two Tests on the tour of the West Indies  this year after suffering concussion following a blow in the nets, but tests revealed that the incident at Lord's was caused by a balance problem in the inner ear and not concussion.
"Speaking to the specialists, they said it was a completely different injury, so that helped," Rogers said.
"It was a really weird sensation. It just looked like [the pavilion] was going from left to right, and almost like my eyes were jumping. That's why I went off."

I heard in the media that he plans to retire from international test cricket after this series. I just don't think the long days in the sun playing test cricket is worth it anymore because the fans are not into it.

Current age 37 years 333 days

At 38  years old he would have played 22 Tests...

Other batsmen at that age : would be past 150 Tests
