Is Verner’s law Applicable to Sanskrit?

"For instance the Gothic strong verb where we find the voiceless
variant in the root-final stage militates against Verner's law. If
Sanskrit does not necessarily retain the archaic feature of PIE
stress---there is no evidence that it does—Verner's application of
shifting stress to Germanic raises problems. Stress is not
characteristic of spoken Sanskrit and modern Indic languages; the
uddatta ("raised" and svarita (a combination of udatta and anudatta )
discussed by Panini in his Grammar are musical tones, and not a matter
of stress. Verner's comparison of shifting Sanskrit syllabic
lengthening to shifting Germanic stress is highly questionable simply
because no voicing or unvoicing takes place in the Sanskrit verbs,
such as pat, cit, vrt and vep, unlike in some Germanic verbs (Thundy
1991, p. 1180)."
