Comment on “Static and spherically symmetric black holes in $\mathrm{f}(\mathrm{R})$ theories”

We consider the interesting “near-horizon test” reported in S. E. P. Bergliaffa and Y. E. C. de O. Nunes, Phys. Rev. D 84, 084006 (2011) for any static, spherically symmetric black hole solution admitted in $\mathrm{f}(\mathrm{R})$ gravity. Before adopting the necessary conditions for the test, however, revisions are needed as we point out in this Comment.
