The Atlanta Falcons placed linebacker Deion Jones on injured reserve on Tuesday Mohamed Sanu Jersey , taking a second 2017 Pro Bowler from the defense in less than a week.The move with Jones comes after coach Dan Quinn on Friday announced safety Keanu Neal suffered a torn ligament in his left knee and will miss the remainder of the season.Jones hurt his foot in Thursday night's 18-12 opening loss at Philadelphia . Quinn said Tuesday that Jones will require surgery, but is expected to return this season."We are bummed for Deion, but we do expect to get him back at some point this season," Quinn said in a statement."He represents all that we are looking for in a Falcon player, and while he will not be on the field for us right now, he will continue to have a presence in our building."The Falcons didn't release further details of Jones' injury or surgery.Jones led the defense with nine tackles, one interception and two passes defensed against the Eagles. It was his seventh career interception.He had 138 tackles, three interceptions and one sack in 2017 when he earned his first Pro Bowl selection.Jones must remain on IR for at least six weeks. He then would have two weeks to return to the roster. The earliest date he could return would be on Nov. 11 for Atlanta's game at Cleveland.Second-year linebacker Duke Riley may take Jones' spot at middle linebacker in the starting lineup. Quinn said Friday a combination of Damontae Kazee and Jordan Richards will be the first options to replace Neal.Jones, a second-round draft pick from LSU in 2016, and Neal have been keys to dramatic improvements on defense under Quinn.In other roster moves on Tuesday, the Falcons promoted running back Brian Hill to the active roster and signed wide receiver Julian Williams to the practice squad. The team also waived defensive tackle Jacob Tuioti-Mariner from the practice squad.Atlanta Falcons 2018 quarter season pace on defense is not pretty We looked at the team’s offensive pace through four games earlier this week, which was pretty encouraging. They’re on pace to blow right by what they did in 2017 in almost every area, and we’ll hope they’ll end the season with a top five offense that somehow pushes them into the playoffs.To get there, though, they’ll have to overcome or improve a defense that’s on pace to set at least one unfortunate team mark. Buckle up for some sobering numbers. Team PacePoints Allowed: 488 (315)Yards Allowed: 6 Authentic Ryan Schraeder Jersey ,488 (5,094)Passing Yards Allowed: 4,544 (3,429)Rushing Yards Allowed: 1,944 (1,665)Penalties: 140 (103) The last time the Falcons allowed that many points in a season? Never. It’s unlikely that the team will continue to be quite this bad if they can get the players they currently have healthy and comfortable, but the picture’s still unlikely to be pretty. You can make a reasonable argument that the defense was playing a bit over its head in 2017, but we’re seeing what happens when you lose 3-4 of your best defenders at once and some of your most reliable starters falter. I really hope we’re not sitting here at the end of this season talking about the Falcons breaking their franchise record for points allowed.

The Falcons also have zero forced fumbles on defense thus far in 2018.
