Lions S Brian Branch suffers torn Achilles

It was reported earlier Friday morning (via NFL Network’s Tom Pelissero) that Branch had been diagnosed with an Achilles injury pending further tests, stirring fears of a tear that would end his season. That will indeed be the case, as it is far too late in the season for Branch to rush back to the field.

The third-year safety limped off the field late in Thursday’s game and was carted back to the locker room. The Lions initially announced that Branch injured his ankle. After the game, he was seen in a walking boot and crutches (via Dave Birkett of the Detroit Free Press), and head coach Dan Campbell confirmed that the injury was believed to be serious.

Branch’s absence will be a huge loss for the Lions defense, especially considering the myriad of other injuries in their secondary. Cornerback Terrion Arnold is out for the season after shoulder surgery and safety Kerby Joseph has not played since Week 6. Two other cornerbacks, D.J. Reed and Ennis Rakestraw, have also missed a significant amount of time.

Branch was one of the few reasons the unit stayed afloat as long as it did. Though the Lions have given up at least 325 passing yards twice in their last three games, they also held their previous three opponents to under 200 yards through the air. Detroit only won three of those six games, putting them at 8-5 and in third place in the NFC North. They trail the Bears (9-3) and Packers (8-3-1) with one win against the former and two losses against the other. The Lions will go to Chicago in Week 18 for a game that could have huge playoff implications.

They will have to make that trip without Branch, who has started all but one game this year. Here are his ranks on the Lions defense: second in passes defended (nine), third in tackles (75) and fifth in sacks (2.5) and tackles for loss (five). In addition to his official counting stats, Branch also has a career-low 4.9% missed tackle rate, per Pro Football Focus (subscription required), and he has done all of this playing a demanding, versatile role with 282 snaps as a free safety, 236 in the box, and 149 in the slot.

With all of that in mind, it is clear that no one player can replace Branch’s multidimensional contributions. The Lions will have to do so in the aggregate, but with so many other defensive backs missing, it could get complicated. Second-year safety Thomas Harper took on Joseph’s more traditional free safety role for six games before he was supplanted by Avonte Maddox on Thursday night. Branch’s injury will likely bring Harper back into the mix. The Lions can use more three-linebacker looks to take care of Branch’s box snaps, and Amik Robertson could slide into the slot when needed. However, with Arnold down, Detroit would then need a No. 2 outside cornerback for nickel looks. That will likely be Rock Ya-Sin.

Branch will now face a long road to recovering, likely with the hopes of returning by the start of the 2026 season. Achilles recoveries have gotten shorter and shorter in recent years with some players opting for a SpeedBridge procedure to accelerate their return timeline. But a major December injury could make it difficult for an athletic, physical player like Branch to get back to full strength in time for the regular season.
