Authentic K'Waun Williams Jersey , call up Najee Toran, sign linebacker Fooch’s update: Kyle Shanahan announced that Brock Coyle suffered a C4 compression fracture in his back. The earliest he could be cleared for contact is six weeks.The San Francisco 49ers announced some transactions Wednesday afternoon. The team has placed linebacker Brock Coyle on injured reserve and signed linebacker Terence Garvin. Additionally, they promoted offensive lineman Najee Toran from the practice squad and signed WR Frank Stephens to the practice squad. The 49ers had one open roster spot on the 53-man roster after placing Dekoda Watson on injured reserve last weekend.The Coyle news is of note given his injury. He was placed in the concussion protocol after suffering a head injury in Week 1. He can return from IR, having been placed on it after final cuts, but this suggests a particularly concerning concussion. Head coach Kyle Shanahan will meet with the media at 12:25 p.m. and should have an update at that point.Garvin can play both inside and outside linebacker, and offers some depth for a depleted group. Elijah Lee was next man up after Coyle’s concussion, but the rotation next to Fred Warner is not yet clear.Toran’s promotion suggests Joshua Garnett and/or Mike Person’s foot injuries might cost them this week. The 49ers will issue a practice participation report Wednesday afternoon which will give us a better handle on things.Shanahan will meet with the media at 12:25 p.m. PT, and the 49ers will stream the press conferences Twitter, Facebook, and the team’s app. The 49ers beat writers will also have updates from the media sessions. I’ve embedded our beat writer Twitter list so you can follow along. We’ll have a transcript later today.A Twitter List by NinersNation The Atlanta Falcons lost yet another starter to a season-ending injury Monday.Yet a team with Super Bowl aspirations is hoping that safety Ricardo Allen's torn Achilles tendon won't derail their season."We will not play the role of the victim with injuries, and we've got a locker room full of tough competitive guys, and I expect us to play well," coach Dan Quinn said Monday Authentic Jimmy Garoppolo Jersey , a day after Allen injured his leg against the Saints.That's a hard sell before Sunday's game against the Bengals, given how important Allen is to the Falcons' injury-ravaged defense. Allen is the third Falcons defensive starter to go on injured reserve so far this season.The Falcons said they're not feeling sorry for themselves even though starting strong safety Keanu Neal was lost for the season with a knee injury in the first game at Philadelphia. Middle linebacker Deion Jones suffered a foot injury that will keep him out at least eight games. Atlanta also has lost starting left guard Andy Levitre to a season-ending arm injury."This is the life we live," defensive tackle Grady Jarrett said. "You can't sit there and worry over it."Allen, a fourth-year veteran from Purdue, is respected for his ability to coordinate the defense on the field.He was carted off the field late in Sunday's 43-37 overtime loss to the Saints, and the Falcons (1-2) have little depth at the position heading into Sunday's game against the Bengals (2-1).Second-year pro Damontae Kazee, a cornerback in college at San Diego State, moved into the lineup after Neal was lost.That bumped the 5-foot-9, 186-pound Allen — a cornerback in college — to strong safety, where he was expected to play a lot of run defense.Jordan Richards, a former second-round pick by the Patriots acquired by a trade days before the season, jumped into the strong safety position upon Allen's injury."It's big. Just got to pray for him," Falcons cornerback Desmond Trufant said. "Big part of the D. Everybody knows what he brings Authentic Kyle Juszczyk Jersey , but other people got to step up."The Falcons have just one other safety on the roster, having signed Keith Tandy a couple of weeks ago. He was inactive for Sunday's game against the Saints.Quinn said that reserve linebacker Kemal Ishmael, a former safety whose primary role has been to play special teams, will be a consideration, and third-year nickel back Brian Poole, will practice at the safety spot.Allen is respected for his overall grasp of the defensive concepts of Quinn and coordinator Marquand Manuel and for his ability to communicate to teammates."That was one of Rico's strengths, just how smart he is, his understanding of what's going on before plays happen on their side and our side," Trufant said.Quinn said the Falcons will look to add another safety to the roster, but rebuffed the suggestion that the team might seek to acquire Seahawks safety Earl Thomas or sign free agent Eric Reid, another former Pro Bowler.
