The COVID-19 list was created this summer for a player who either tests positive for or who has been quarantined after having been in close contact with an infected person or persons.
Players will remain on the list until they are medically cleared to return.
Williams, 27, originally signed on with the Rams as an undrafted free agent out of Auburn in 2016 but was waived coming out of the preseason. After a few years, the Bills signed him to a futures contract back in January of last year.
Williams was among their final roster cuts this offseason and re-signed to their practice squad. He was promoted to the active roster in October.
In 2019, Williams appeared in four games for the Bills and caught 12 passes for 166 yards receiving and one touchdown.
Taylor, 26, is a former sixth-round pick of the Dolphins back in 2017. He was entering the third year of his four-year, $2.55 million contract when Miami cut him loose coming out of the preseason.
Taylor later signed on to the Bills’ practice squad before being promoted late last season.
In 2019, Taylor appeared in three games for the Bills and recorded six tackles and no sacks.
