Er sagt, er könne sich an den Abend nicht erinnern.

English Translation

He says that he has no memory of the evening.

Why not “Er kann sich…”?

It is reported speech, and therefore you need the Konjunktiv (1).

That said, in everyday oral communication you will often hear “Er sagt, er kann …”.
Nevertheless, it’s wrong.

Thank you!

I’ve been told as well “Er, könnte sich…” would also be used, even if it is wrong!

That’s true.
“Er sagt, er könnte …” or “Er sagt, er würde …” are also common mistakes.

Nobody will care, if you say that one way or the other.
But don’t write it.
