Moore (shoulder) will be placed on the Falcons' injured reserve/designated to return list, ESPN reports.

Moore suffered a serious shoulder injury during Sunday's game and will consequently be ruled out for the foreseeable future, representing a major blow to a Falcons team currently ranked second-last in total defense. The 29-year-old entered this season coming off a career-year that included 86 tackles (67 solo), three interceptions, three forced fumbles, two forced fumbles, two sacks and seven pass defenses last year. Once Moore was forced to exit Sunday's game, second-year player Kemal Ishmael replaced him at strong safety and defensive coordinator Mike Nolan also deployed regular three-safety sets, with rookie Dez Southward joining veteran free safety Dwight Lowery and Ishmael at the back.

Moore's teammates were not optimistic about the safety's shoulder injury after Sunday's game, ESPN reports.

Moore, who had 16 tackles (nine solo) and a forced fumble through three games, was replaced by Kemal Ishmael. The 29-year-old Moore produced across the board last year, piling up 86 tackles (67 solo), three interceptions, three forced fumbles, two forced fumbles, two sacks and seven pass defenses. He had a similarly excellent stat line in 2012, albeit over just 12 games.

Updating a previous item, Falcons SS William Moore was arrested on a simple battery charge for "grabbing a woman's shoulder."

Falcons SS William Moore was arrested and charged with simple battery on Thursday.

Moore was booked into the Fulton County Jail, but there are no further details at the moment. The soon-to-be 28-year-old agreed to a five-year, $29.5 million extension last month. It's Moore's first run-in with the law since entering the league, so there's a possibility he could avoid suspension.

Falcons have agreed to terms on a five-year contract with SS William Moore.

The Falcons opted not to franchise tag Moore, and there was some speculation that he'd hit the open market. It was wise that Atlanta didn't let that happen. Moore was the top safety in this year's free agency class, and is a favorite of Rotoworld's Jeff Ratcliffe. Pencil him in as a strong DB option in IDP leagues.

The Falcons have "ramped up" negotiations with free agents William Moore and Sam Baker.

Free agent SS William Moore hopes to re-sign with the Falcons.

Moore, who is keen on letting the market establish his value, wasn't franchise tagged ahead of Monday's deadline. He says his agent is in ongoing talks with the Falcons. "I hope to get it closed soon. I love the Atlanta Falcons. They gave me an opportunity to be blessed and come into the NFL and be a part of this great organization."

The Atlanta Journal-Constitution expects free agent SS William Moore to get five years and $25-30 million on his next contract.

We'd say those numbers are a bit conservative, but they're close. Tennessee signed Michael Griffin to a five-year, $35 million contract with $15 million guaranteed last offseason as he was entering his age-27 season, and Moore is arguably a better player as he enters his age-28 campaign. Atlanta does not intend to use the franchise tage before Monday's deadline.

CBS' Jason La Canfora confirms the Falcons "do not intend" to use the franchise tag.

There have been varying reports on the Falcons' intent for the tag, but it's looking safe to assume they won't apply it ahead of Monday's deadline. The Falcons are now nearly $16 million under the cap after releasing Michael Turner, John Abraham and Dunta Robinson, so the space is there if they change their mind. SS William Moore is the most obvious candidate.

Contrary to earlier reports, Profootballtalk.com reports the Falcons have not ruled out using the franchise tag, and that free agent SS William Moore is the "most obvious candidate."

NFL.com's Ian Rapoport reports the Falcons are not expected to use the franchise tag.

It's a surprise, since the Falcons have a readymade candidate in free agent SS William Moore, whom they consider a priority to re-sign. The St. Louis Post-Dispatch recently reported Moore was "interested in testing" the open market. The Falcons must be confident they can reach a long-term deal before the deadline to apply the tag on March 4. If not, Moore could be heading for a bidding war in free agency.

League sources tell the St. Louis Post-Dispatch that free agent SS William Moore is "interested in testing" the open market.

He may not get that chance if the Falcons slap Moore with the franchise tag. A movable chess piece playmaker in Mike Nolan's defense, Moore was an integral part of the Falcons' pass-coverage and run-defense schemes. Moore turns 28 in May. He's one of the top free agent safeties available, behind Jairus Byrd.

ESPN's Adam Schefter calls impending free agent SS William Moore a "prime candidate" for the Falcons' franchise tag.

A three-year starter and cornerstone of the Falcons' secondary, Moore is hoping to test his value on the open market. He might not get there. The tentative franchise tag number for safeties in 2013 is a relatively inexpensive $6.798 million. The Falcons could very well slap Moore with the tag and the evaluate the situation in 2014 -- when he'll be entering his age-29 season.
