The Niners announced Monday that Bourne was being placed back on that list, just days after he’d been activated from it following a week in which he tested positive then registered multiple negative tests in a row.
Bourne was activated from the list on Friday after he went on it Wednesday evening. Bourne first received a positive test last Wednesday, which led to the Niners shutting down their facility and entering the league’s intensive protocols.
Additional contact tracing led to left tackle Trent Williams and wideouts Deebo Samuel and Brandon Aiyuk being designated as high-risk close contacts of Bourne’s. All four were subsequently placed on the reserve/COVID-19 list and ruled out of Thursday’s game against the Green Bay Packers.
But Bourne registered negative test results on Thursday and Friday, which led to all four players being activated from the list. Had the game against the Packers been played on Sunday, the Niners would have had that quartet available, though Samuel would not have played because of a hamstring injury.
