Bills place LB A.J. Klein on Reserve/COVID-19 list

Klein signed a three-year pact with the Bills back in 2020, and he started 11 of his 16 games during his first season in Buffalo, finishing with career-highs in tackles (75), sacks (five) and QB hits (nine). He also started one of his three playoff appearances. The 30-year-old has started only three of his 11 games this season, collecting 30 tackles.

The linebacker has been completely phased out of the defense in six appearances this year, but he’s seen significant roles in his other five appearances. As Joe Buscaglia of The Athletic tweets, Monday night could have been one of those games in which Klein saw time on defense, as the Bills could have relied on a three-linebacker look against the Patriots’ “fullback heavy approach.”

The Bills also promoted two players from the practice squad for Monday night’s game (via Aaron Wilson on Twitter): nose tackle Eli Ankou and linebacker Joe Giles-Harris. Ankou has seen time in 29 career games, including an appearance with Buffalo in Week 12. Giles-Harris got into 14 games with the Jaguars between 2019 and 2020, and he’s spent most of the 2021 campaign on Buffalo’s practice squad.
