The Chargers’ 2026 season hinges on the health of Joe Alt and Rashawn Slater. After a torn patellar tendon ended Slater’s year and ankle surgery sidelined Alt, their return to full strength could determine whether this offensive line becomes a strength — or a major concern.
The foundation of the Chargers’ 2026 season won’t just be scheme, cap space or skill-position upgrades. It will be much simpler than that: the health of Joe Alt and Rashawn Slater.
When both tackles are on the field, the Chargers have one of the most physically gifted bookend duos in the league. When they’re not, everything changes — protection schemes tighten, the run game becomes inconsistent and the offense is forced to adjust instead of dictate.
Rashawn Slater’s 2025 season ended before it ever truly began. During training camp, Slater suffered a torn patellar tendon — a devastating knee injury that sidelined him for the entire year. It was a crushing blow for a team that had just committed to him long term and was counting on him to anchor the left side. A patellar tendon tear is not a minor injury; it requires extensive rehab and can take time before a player regains full explosiveness and lateral movement.
At full strength, Slater is one of the premier left tackles in football. His footwork, balance and ability to mirror elite pass rushers allow the offense to function without constant help to the blind side. Without him, the Chargers were forced to shuffle protections and rely more heavily on chips and quicker-developing concepts. That limits the offense’s ceiling, particularly in a conference filled with high-end edge rushers.
Joe Alt’s season was also disrupted by injury. Alt dealt with multiple ankle issues throughout 2025, first suffering an ankle sprain early in the season. Though he returned, the injury lingered and was eventually aggravated again, leading to season-ending ankle surgery. The repeated setbacks robbed the offensive line of consistency and continuity.
When healthy, Alt showed exactly why he is viewed as a cornerstone tackle. His size, length and technique give the Chargers stability on the right side, and his presence helps balance the line when paired with Slater. But ankle injuries — especially recurring ones — can impact a lineman’s ability to anchor and redirect against speed rushers. For a young tackle expected to protect the edge against elite competition, mobility and stability are critical.
The ripple effect of both injuries was clear. The Chargers struggled at times to maintain clean pockets, and the offense was forced to operate with less margin for error. Deep drops and longer-developing play-action concepts become far more difficult when the tackles are either unavailable or playing at less than full strength. Even the run game suffers when edge setting becomes inconsistent.
Looking ahead to Week 1 of 2026, optimism remains that both Slater and Alt will be fully cleared and ready to go. An entire offseason of rehab should allow Slater to continue rebuilding strength in his knee, while Alt’s ankle surgery was performed with the expectation of a full recovery.
If both return at full strength, the Chargers’ offensive identity immediately stabilizes. The protection improves. The playbook expands. The quarterback operates with confidence. The run game finds balance. In a competitive AFC landscape, that kind of stability up front is not a luxury — it’s a necessity.
However, if either player is limited or unavailable, the margin for error shrinks considerably. The difference between contender and pretender in today’s NFL often comes down to offensive line play.
For the Chargers, 2026 begins with two names: Joe Alt and Rashawn Slater. Their health will go a long way toward determining just how high this team can climb.
