Spector (calf) reverted to Buffalo's injured-reserve list Thursday, Aaron Wilson of KPRC 2 Houston reports.

EDGE Analysis

Spector wasn't claimed by another team after he was waived by the Bills on Wednesday with an injury designation. He'll go on the Bills' IR, which will force him to sit out for the entire 2025 season unless he can reach an injury settlement with the team. Spector appeared in 11 regular-season games (four starts) for the Bills in 2024 and posted 40 tackles (22 solo), including 1.5 sacks, and one fumble recovery.

Spector (calf) was designated as waived/injured by the Bills on Wednesday.

EDGE Analysis

Spector will revert to injured reserve if he clears waivers. While he's dealt with injuries ever since being drafted in 2022, the 26-year-old has made a decent impact when healthy, tallying 40 tackles over 11 regular-season games in 2024, but has never played more than 11 games in any of his three campaigns. His current calf injury goes all the way back to last season, which caused him to miss much of the remainder of the regular season and playoffs.

Spector (calf) exited practice early Monday, Alaina Getzenberg of ESPN.com reports.

EDGE Analysis

Spector had been dealing with a calf injury since Week 10 of the 2024 season, which caused him to miss nine games total, but he was participating in OTAs back in July. It's unclear if the 26-year-old aggravated the injury Monday or if it's a separate calf issue, but if he's out an extended period of time, it could impact his chances of making the final 53-man roster.

Spector (calf) participated in Wednesday's practice, Maddy Glab of the Bills' official site reports.

EDGE Analysis

Spector dealt with a calf injury for the entire 2024 season, which caused him to miss nine games (including the Bills' three playoff games). He looks to be fully healthy for the start of training camp, and Glab relays that the 2022 seventh-rounder made a strong impression during Wednesday's practice. Although injuries limited his playing time in 2024, Spector still finished the regular season with a career-high 40 tackles (22 solo), including 1.5 sacks, and one fumble recovery across 11 games.

Spector (calf) tallied 40 total tackles (22 solo), including 1.5 sacks, across 11 regular-season games in 2024.

EDGE Analysis

Spector dealt with a calf issue for the entirety of his 2024 campaign, sustaining the injury in August and missing nine of the Bills' games, including their three playoff contests. However, the third-year linebacker was relatively productive when healthy, posting career highs in tackles, sacks and defensive snaps played (278). Spector is entering the final season of his rookie deal in 2025 and will likely remain one of the Bills' top reserve linebackers, with starters Terrel Bernard and Matt Milano still under contract next season.

Spector (calf) has been ruled out for Sunday's AFC Championship Game against the Chiefs.

EDGE Analysis

Spector was designated to return from injured reserve Wednesday and was a full participant in all three practices this week. However, the 2022 seventh-round pick has not progressed enough in his recovery from a calf injury to play in Sunday's playoff bout. Joe Andreessen will continue to see extra time at linebacker alongside Terrel Bernard and Matt Milano while Spector remains on IR.

Spector (calf) practiced in full Friday and is officially listed as questionable for Sunday's road AFC Championship Game against the Chiefs, though he officially remains on IR.

EDGE Analysis

Spector will need to be activated to the 53-man roster by Saturday's deadline in order to be eligible to play Sunday. If cleared to play, he figures to contribute in a rotational role among Buffalo's linebacker corps in his first game back in action.

The Bills designated Spector (calf) to return from injured reserve Wednesday, Alaina Getzenberg of ESPN.com reports.

EDGE Analysis

Spector suffered a calf injury during the Bills' Week 16 win over the Patriots, which was severe enough for him to be placed on injured reserve. He's placement on IR resulted in him missing the last two games of the regular season and the first two games of the playoffs. Spector can participate in practice Thursday and Friday, though he would have to be activated from IR in order to play in Sunday's AFC Championship Game against the Chiefs.

The Bills placed Spector (calf) on injured reserve Tuesday.

EDGE Analysis

Spector suffered a calf injury in the third quarter of this past Sunday's 24-21 win over the Patriots, and the issue is severe enough for him to warrant a stint on injured reserve. He'll be required to miss at least the next four games, which means he will not be available for the Bills' final two contests of the 2024 regular season. However, Spector could return for the postseason if Buffalo makes a deep playoff run. Spector will finish the 2024 regular season with 40 tackles (22 solo), including 1.5 sacks, and one fumble recovery across 11 games.

Spector (calf) is doubtful to return to Sunday's game against New England, Alaina Getzenberg of ESPN.com reports.

EDGE Analysis

Spector injured his calf in the third quarter of Sunday's game. With his day likely done, Dorian Williams will see more snaps at linebacker alongside Terrel Bernard and Joe Andreessen for the rest of Sunday's game.
