No creer que + subjunctive

[fglorca]

Given that 'no creer que' always takes a subjunctive, are the following three correct:

I don’t think she 'is' badly injured:
No creo que 'esté' herida seriamente.

I don’t think she 'was' badly injured:
No creo que 'fue' herida seriamente.

I didn’t think she 'was' badly injured:
No creía que 'fuera' herida seriamente.

The middle one is not correct, since the subjunctive wasn't used in the subjunctive clause.
