EAST RUTHERFORD, N.J. -- The Giants will be without defensive tackle Chris Canty and tight end Travis Beckum for at least the first six games of the season as they placed both injured players on the Reserve/Physically Unable to Perform list on Monday.

The moves are not surprising since Canty and Beckum were both on the training camp PUP list and have both been recovering from offseason knee surgery.

The Giants also placed offensive lineman Brandon Mosley, one of the team's fourth-round picks, on injured reserve with an ankle injury. And to reduce the roster to 75, the Giants waived cornerbacks Antwaun Molden and Brandon Bing tight ends Ryan Purvis and Christian Hopkins, defensive tackles Carlton Powell and Oren Wilson, safety Chris Horton and Jojo Nicolas, wide receivers Julian Talley and Brandon Collins and running back Joe Martinek.

But the biggest move clearly is Canty. Ever since Canty wasn't ready to practice at the start of camp, the defensive tackle was in danger of missing the beginning of the season.

The Giants will now have to wait until mid-October at the earliest for Canty to return. It's quite possible that Canty may not be ready to play until November if the team eases him back into the mix. They'll have to play Dallas, Tampa Bay, Carolina, Philadelphia, Cleveland and San Francisco at the very least without their starting defensive tackle for the past two seasons.

The Giants had trouble stopping the run for much of last season and now they are staring at going into the season without Canty, defensive tackle Shaun Rogers (blood clot) and Marvin Austin (back). Linval Joseph and Rocky Bernard will start inside.

Who backs those two up remains to be seen with Austin sidelined. The team will cut its roster down to 53 on Friday and Marcus Thomas, seventh-round pick Markus Kuhn and Dwayne Hendricks all have a chance to make the final roster. Kuhn has impressed the coaching staff in the preseason.

As for Beckum, he is still recovering from a torn ACL suffered in the Super Bowl. The Giants will move forward with Bear Pascoe and Martellus Bennett as their starting tight ends. Larry Donnell and fourth-round pick Adrien Robinson are still on the roster and it will be interesting to see what they do on Friday with those two.
