Courts are reviewing many cases after a rights commission, formed by King Hamad bin Isa Al-Khalifa after the crackdown. The state news agency BNA said the Court of Cassation had overturned the death sentences for the two Bahrainis on Monday as well as a life jail sentence for one other.
The original verdicts were handed down by a military court in May but the Bahrain Independent Commission of Inquiry (BICI) criticized the military courts in its report issued in November.
The men face a retrial in a civil court, BNA said. The incident happened during an operation to retake control of a traffic roundabout in Manama which had become the center of the protests in February and March.
The government says Iran is fomenting the unrest, a charge opposition figures and activists deny.
Opposition groups are demanding a retrial or revoking of sentences in other cases. These include that of 21 political figures, rights activists and a blogger accused of leading the protests to change the political system violently. Eight of them received life sentences.
