Njoku's Knee Is the Third Fracture. The Chargers' Depth Chart Has No More Give.

The depth chart the Chargers entered 2026 with was already a structural argument, not a roster. Jacob Spomer — an undrafted free agent — is starting at center because Tyler Biadasz tore his ACL in August. Ladd McConkey, who led this team in receiving yards last season, is listed questionable with cracked ribs heading into Week 3. And now David Njoku, the tight end the Chargers signed specifically to give Justin Herbert a reliable weapon in the middle of the field, left Sunday's game against the Raiders on a medical cart in the second quarter with a right knee injury. Three positions. Three simultaneous crises. The cascade that started with Biadasz's cart ride on August 18th has not stopped moving.

What makes the Njoku injury particularly damaging is what it exposes about the Chargers' contingency planning. The tight end depth chart behind him reads Charlie Kolar, Oronde Gadsden, Patrick Herbert — the latter being the quarterback's brother, signed as a camp body. That is not a rotation built to absorb a starter going down in Week 2. When Biadasz went on IR, the front office scrambled to put Spomer and Rodney Shelley on the 53-man roster. When McConkey got hurt, they signed Marquez Valdes-Scantling to the practice squad. At tight end, there is no equivalent emergency valve to pull.

The receiver situation is worth examining as a parallel, because it tells you something about how this organization responds under pressure. Valdes-Scantling is a two-time Super Bowl champion with real NFL pedigree — a legitimate addition, not a token move. But he is on the practice squad, not the active roster, and McConkey is still listed questionable. Quentin Johnston, who had 755 yards and eight touchdowns in 14 games last season, is healthy and available, which matters. But Herbert built his 2025 efficiency — 3,886 passing yards, 26 touchdowns — on a receiving structure that spread the ball across multiple reliable targets. Strip out McConkey and Njoku simultaneously and that structure gets very thin very fast.

Here is the number that should concern Chargers fans most, though it comes from last season rather than this one: this team went 6–2 in games decided by seven points or fewer. That close-game excellence was the primary reason they finished 11–6 despite a point differential that suggested they should have won considerably fewer. Close-game records are notoriously fragile — the most volatile predictor of future performance in the sport. A team that was already living on the edge of its margin now heads into Week 3 with a fractured offensive line anchored by an undrafted rookie, its leading receiver from last year nursing ribs, and its new starting tight end on a cart. The margin for error has not just shrunk. It has disappeared.

My read is that the Chargers are now in genuine danger of losing games they would have found ways to win last season — not because Herbert isn't good enough, but because the infrastructure around him has been stripped down to the studs. The offensive line crisis was the story of August. McConkey's ribs were the story of Week 1. Njoku's knee is the story of Week 2. At some point, the story stops being about individual injuries and starts being about a roster that was never deep enough to absorb all of them at once. That point arrived Sunday, in the second quarter, on a medical cart rolling off the field in Las Vegas.
