A.J. KLEIN NEWS

Announces retirement Klein announced Tuesday that he was retiring from the NFL, Alaina Getzenberg of ESPN reports.

Impact Klein will retire after playing 11 seasons in the NFL for five different teams. The 33-year-old, who was a free agent before announcing his retirement, most recently played for the Bills, where he played in two regular-season games during the 2023 campaign but failed to record any stats.

Elevated ahead of KC game The Bills elevated Klein to the active roster Saturday.

Impact Klein played a key role in the Bills' win over the Steelers in the wild-card round after the team suffered several defensive injuries. He ended up playing 67 percent of the defensive snaps -- his first action since Week 10 against the Broncos -- while recording a game-high 11 tackles. With Matt Milano out for the season and Baylon Spector ruled out for Sunday due to a back injury and starter Terrel Bernard (ankle) listed as questionable, Klein may be asked to step up again, a task that will be a little more difficult against Patrick Mahomes instead of Mason Rudolph.

Claimed by Bills The Bills claimed Klein off waivers from the Bears on Thursday.

Impact The 31-year-old was initially acquired by Chicago as part of a trade that sent middle linebacker Roquan Smith to the Ravens in early October. However, Klein suited up for only nine special-teams snaps over two contests with the Bears, and he was waived by the team Tuesday. The 10th-year linebacker spent the last two seasons with Buffalo, recording 110 tackles, five sacks, nine passes defended and an interception over 31 regular-season games, and his experience with the team should help him to carve out a reserve role behind middle linebackers Tremaine Edmunds (groin) and Tyrel Dodson.

Impact Klein was released by the Bills in March after dropping into a rotational role at linebacker last season.
