The Chargers will be shorthanded along the offensive line during their Week 4 game against the Chiefs. They are on track to have Justin Herbert available, however. 
Los Angeles’ franchise passer is expected to play tomorrow, Ian Rapoport, Tom Pelissero and Mike Garafolo of NFL Network report. As long as a last-minute setback does not occur regarding Herbert’s high ankle sprain, he will be in the lineup against Kansas City. ESPN’s Jeremy Fowler adds Herbert made it through the practice week without issue and that he is feeling better now than he was ahead of last week’s contest.
That game saw the 26-year-old exit after taking a sack which aggravated his ankle sprain. Herbert’s availability was in doubt for the following contest, but he quickly expressed optimism he would be able to suit up for Week 4. Signs pointed in that direction midweek, so today’s update comes as little surprise. Herbert will likely have two backup offensive tackles protecting him as he aims to play a full game, though.
Left tackle Rashawn Slater has been ruled out due to the pectoral injury he suffered last week. Rookie right tackle Joe Alt, meanwhile, has been downgraded to doubtful as a result of his MCL sprain. This year’s No. 5 pick is expected to miss time, so he is likely to join the likes of Slater and edge rusher Joey Bosa on the inactive list tomorrow.
The Chargers started 2-0 to kick off Jim Harbaugh‘s tenure as head coach, but Week 3 resulted in a 20-10 loss to the Steelers. The team’s offense was entirely ineffective during the second half, a discouraging sign for backup quarterback Taylor Heinicke if he finds himself back on the field at some point on Sunday. If all goes well, though, it will be Herbert in place throughout the contest.
