The Giants announced that they have placed Geoff Schwartz on injured reserve. As previously reported, the Giants will be adding guard Adam Gettis to the active roster off of the Raiders’ taxi squad.

The entire Giants offensive line has been finding it difficult to stay on the field this season. Former first-round pick Justin Pugh was ruled out for Sunday’s contest with a concussion, his second-straight game missed with that injury. Center Weston Richburg was also sidelined on Sunday with a high ankle sprain. John Jerry, Dallas Reynolds, and rookie Bobby Hart have been seeing unexpected playing time because of the rash of injuries to the interior of the offensive line.

Schwartz struggled with injury for the Giants last year, when he played in only two games after signing a decent-sized free agent contract the previous offseason. The team has yet to get a return on investment for the four-year deal worth $16.8MM and $6.2MM guaranteed. Now, it’s fair to wonder what Schwartz’ future will be with Big Blue beyond 2015.

The Dolphins have waived/injured veteran defensive tackle C.J. Mosley, according to James Walker of ESPN.com (on Twitter). Mosley signed a one-year, minimum salary deal with Miami in June.

By signing with Miami this summer, Mosley reunited with former teammate Ndamukong Suh, the offseason’s No. 1 free agent who signed with the club much earlier in the offseason. Although he wasn’t as coveted a free agent as his ex-Lions teammate, Mosley was a solid contributor in Detroit last season as well. Pro Football Focus’ grades ranked him 26th out of 81 qualified defensive tackles, viewing him as slightly above average against both the pass and the run.

This year, however, Mosley was not as effective as the Dolphins hoped he would be. A calf issue had Mosley listed as questionable for Sunday against the Ravens and that injury will probably be listed as the formal reason for his departure.

Mike Tannenbaum, the Dolphins’ executive vice president of football operations, was the general manager in New York when Mosley played for the Jets from 2006 to 2008.

Today’s workouts from around the league:

• The Raiders worked out linebacker Emmanuel Acho, safety Stevie Brown, safety Chris Clemons, defensive back Chris Hackett, defensive end/outside linebacker Adrian Hubbard, and linebacker Colton Underwood, according to Aaron Wilson of the Houston Chronicle (on Twitter).
• The Colts worked out tight end Cameron Clear, cornerbacks Jeremy Harris and Corey White, and safety Chris Hackett last week, Wilson tweets.
• The Packers worked out wide receiver Ify Umodu, quarterback Matt Behrendt, cornerback Brandon McGee, wide receiver Denarius Moore, and wide receiver Larry Pinkard, Wilson tweets.
• The Bengals worked out defensive backs Brandon Ghee, Robert McClain, and Corey White, Wilson tweets.
• The Chiefs worked out linebackers Thomas Keiser and Andy Studebaker, Wilson tweets.
• The Lions worked out former Falcons linebacker Joplo Bartu, Wilson tweets.
• The Broncos worked out offensive lineman Isaiah Shelton last week, Wilson tweets.
• The Browns worked out safety Sean Baker and linebacker Colton Underwood last week, Wilson tweets.
• The Jets auditioned linebacker Ryan Mueller last week, Wilson tweets.
• Washington worked out defensive back Al Louis-Jean, Wilson tweets.
• The Jaguars worked out defensive back Brandon McGee, according to Wilson (on Twitter).

Browns quarterback Josh McCown is done for the season with a fractured collarbone, coach Mike Pettine told reporters (Twitter link via Ian Rapoport of NFL.com). When asked about who will start the team’s upcoming game, Pettine indicated that things are still up in the air.

McCown finishes the year with fairly respectable numbers. The Browns only won one of his eight starts, but he completed 63.7% of his passes, throwing for 2,109 yards, 12 touchdowns, and just four interceptions. Having signed a three-year contract with Cleveland, McCown still has some guaranteed money left on his deal in 2016, so he’s a good bet to return either as the starter or backup.

Here are Tuesday’s minor signings, cuts, and other moves from around the NFL, with the latest moves added to the top of the list throughout the day:

• The Bills created two openings on their 53-man roster with a pair of Monday moves, and opened up a third vacancy by officially placing Kyle Williams on IR today, tweets Mike Rodak of ESPN.com. The move had been expected since last week.
• To fill those three spots on their roster, the Bills signed defensive end Lavar Edwards off the Cowboys‘ practice squad, defensive lineman T.J. Barnes off the Jets‘ practice squad, and linebacker Kevin Reddick via free agency, per Rodak (all Twitter links). The series of signings helps the team fortify its banged-up defensive line, while also re-adding Reddick, who was cut prior to the regular season.
• The Dolphins have re-signed center/guard Jacques McClendon to their 53-man squad as an insurance policy for Mike Pouncey, the team announced today (via Twitter). Pouncey is dealing with a minor foot sprain and is considered day to day for now. Miami waived linebacker James-Michael Johnson in a corresponding move.
