Hernandez was placed on the COVID-19 injured list after testing positive for the virus Friday, Bill Koch of The Providence Journal reports.
A positive test typically means a player is forced to be out for 10 days, but per Pete Abraham of The Boston Globe, Hernandez could miss less time because he is vaccinated. Christian Arroyo was also placed on the COVID-19 list as a close contact, so the Red Sox will be without both of their main second base options for an extended period. Infielders Yairo Munoz and Jonathan Arauz were recalled from Triple-A Worcester and figure to man the position in the interim. Travis Shaw could also be a candidate to handle the keystone, though it's unclear if Boston will consider going that direction given he hasn't played there since 2019.
