Chargers tight end Antonio Gates is halfway to the best season of his NFL career. But the second half of his season might be rough.

Gates has been listed as doubtful for Sunday’s game against the Texans with a toe injury that he has described as “the worst feeling in the world.”

So Gates, who’s averaging a career-high 16.6 yards a catch and is on pace for career-highs in yards (663 through eight games) and touchdowns (nine), almost certainly won’t be on the field on Sunday.
