Casillas (neck) was placed on injured reserve Wednesday, Adam Caplan of SiriusXM Radio reports.

EDGE Analysis

Casillas started at weak-side linebacker this season, accruing 35 tackles (25 solo). This season has been up and down for the Giants, but with no playoff hopes left, there's no reason to put Casillas back on the field and risk the veteran's health. This was the last season of Casillas' contract, so he may have played his last game for New York.

Casillas (neck) has been ruled out for Sunday's game against the Raiders, Ralph Vacchiano of SportsNet New York reports.

EDGE Analysis

Casillas was able to play through this injury in his last three games, so he may have suffered a setback at some point. The veteran linebacker has 35 tackles (25 solo) through eight games, and Akeem Ayers and Kelvin Sheppard to take over for the time being.

Casillas (neck) is listed as active for Thursday's game against the Redskins.

EDGE Analysis

Casillas was a late addition to the injury report Wednesday, but he was still able to practice fully. Thus, it is not surprising that he will be active for Thursday's game. With the Giants dealing with several injuries at linebacker, the veteran could be in line for a heavy workload.

Casillas (neck) is listed as questionable for Thursday's game against the Redskins.

EDGE Analysis

Casillas didn't crop up on the injury report until Wednesday and was listed as a full participant in the Giants' estimate of what his level of involvement would have been had the team held practice, so it seems likely he'll suit up Thursday. He should be in store for a near-every down role in the Week 12 matchup, but with no more than six tackles on the season, Casillas doesn't carry much IDP appeal.

Casillas (neck) is active for Sunday's game against the 49ers.

EDGE Analysis

The Giants had already ruled out three linebackers (Keenan Robinson, B.J. Goodson and Devon Kennard) due to injury earlier this week, so Casillas' return from a three-game absence comes at a fortunate time. Despite seeing hefty snap counts in his first five appearances of the season, Casillas only managed 19 tackles and no turnovers, limiting his IDP utility as a result.

Casillas (neck) is listed as questionable for Sunday's game against the 49ers, Art Stapleton of The Bergen Record reports.

EDGE Analysis

If Casillas could return this week, it would be quite timely since five of the Giants' top-six linebackers are dealing with injuries. When he was healthy, the 30-year-old linebacker still didn't produce flashy numbers this season, with no games of over five tackles.

Casillas (neck) is listed as out for Sunday's game against the Rams, Dan Duggan of NJ.com reports.

EDGE Analysis

Casillas wasn't able to participate in practice at full speed this week, so this doesn't come as a complete surprise. Since neck injuries have tricky recovery periods, the veteran linebacker will likely need a full practice before he's truly ready to get back on the game field. Keenan Robinson will continue seeing a hefty workload in Casillas' absence.

Casillas (neck) won't suit up for Sunday's matchup with the Seahawks, Jordan Raanan of ESPN.com reports.

EDGE Analysis

Casillas will miss his second straight week with this injury after he left early in Week 5 against the Chargers. The fact that he didn't practice in any capacity this week doesn't bode well for his recovery, and Keenan Robinson will continue filling his vacancy.

Casillas (neck) was held out of Thursday's practice.

EDGE Analysis

Casillas is still recovering from a nerve issue in his neck and could be in line to miss a second straight game, given that he has yet to put in a full practice since suffering the injury in the Giants' Week 5 loss to the Chargers. Keenan Robinson would likely start at weak-side linebacker if Casillas is unable to play Sunday against the Seahawks.

Casillas (neck) is ruled out for Sunday's game against the Broncos, Jordan Raanan of ESPN.com reports.

EDGE Analysis

This will be the first game this season that Casillas misses, and his next opportunity to suit up will be Week 7 against the Seahawks. He has recorded 19 tackles (16 solo) over the first five games, and a quick return would help the Giants' make up for an injury-riddled offensive unit.
