Wikipedia writes on the page of the Battle of Asculum that we have the accounts of Plutarch, Cassius Dio, and Dionysius of Halicarnassus about the fight.

The page on Publius Decius Mus, the consul of 279 writes that according to one tradition the consul died in the battle, according to one, he survived.
https://en.wikipedia.org/wiki/Publius_Decius_Mus_(consul_279_BC)
But in the three accounts mentioned before I have not found mentions of the consul's death. Plutarch doesn't mention him at all, while Cassius Dio and Dionysius both use the phrase "consuls" after the battle, which implies to me that both of them survived.
Who is wrong here?
Am I the one who can't read, and somehow missed the part where it is said that Decius fell in the battle?
Is the wiki page on Asculum wrong, and there is a fourth account of the battle which states that Decius died?
Is the wiki page on Publius Decius wrong, and there is actually no tradition according to which he fell at Asculum?
EDIT:
The translations I read:
Plutarch http://classics.mit.edu/Plutarch/pyrrhus.html
Dionysius https://penelope.uchicago.edu/Thayer/E/Roman/Texts/Dionysius_of_Halicarnassus/20*.html
Cassius Dio https://penelope.uchicago.edu/Thayer/E/Roman/Texts/Cassius_Dio/10*.html
Decius Mus' devotio against Pyrrhus is at Cic., Fin., 2.61 and Cic., Tusc., 1.89. Cicero alone attests to this. There was a tradition that the elder Decius Mus' sons, both Decius Mus, vowed themselves in devotio during their consulship--the middle Decius is mentioned by both Cicero and Livy alongside the father and the grandson. Cicero does not specifically say where the grandson vowed himself, only that it was during the war with Pyrrhus, but presumably he must mean at Asculum.
