Earlier reporting — before the Kansas City game
Joe Alt is expected to miss Sunday's game against Denver with a neck injury, Ian Rapoport reported Wednesday evening. The Chargers have no plans to put him on injured reserve, according to Rapoport. Their official first practice report also lists left tackle Rashawn Slater and receiver Ladd McConkey as nonparticipants, adding concrete availability concerns to an offense that has opened 0-4.
Alt's expected absence is an attributed report, and Wednesday's participation list is not the final game-status report. Los Angeles has not cleared McConkey or named a complete replacement offensive line for Sunday. The game at SoFi Stadium is scheduled for 4:05 p.m. Eastern.
The official report lists Slater with an ankle injury, McConkey with a foot injury, Trevor Penning with a concussion and Kayode Awosika with a fibula injury. All four did not practice. That leaves availability questions across the line as well as at receiver. Quentin Johnston was limited with a chest injury; his participation should not be treated as a declaration that he will play.
Rapoport's update narrows the immediate outlook for Alt while leaving his longer absence unsettled. Avoiding injured reserve would keep the team from making that particular roster move, but the report does not establish when he will return. RSO managers evaluating Justin Herbert, Omarion Hampton or the receivers have a practical reason to follow the protection decisions through Friday.
The reshuffle began in Sunday's loss at Seattle. Travis Burke replaced Alt at right tackle. Logan Taylor first filled in for Penning at left guard, then moved to left tackle after Slater went out. Jake Slaughter moved from center to guard, undrafted rookie Jacob Spomer entered at center, and Cole Strange completed the line on the final drive, according to the Chargers' official Monday account. Those were the players used in that game; Wednesday's report does not make them the announced starting five against Denver.
Adam Gretz's Wednesday evening report for Yardbarker independently described the combined loss of protection and receiving options. It is the combination that matters for lineup planning: a weakened line can change the work an offense can execute, while McConkey's uncertain availability creates another decision. The evidence supports watching the next two practice reports and Sunday's active list before assigning replacement targets or a changed workload.
Jim Harbaugh's earlier assurance that Mike McDaniel will remain offensive coordinator still stands as the team's public coaching position. The fresh development is who can take the field to run the offense.
