McConkey caught just one of his five targets for 12 yards in the Chargers' 22-19 overtime win over the Eagles on Monday.
The entire Los Angeles passing attack struggled to do much of anything as Justin Herbert was pressured on close to 60 percent of his dropbacks. It's at least encouraging the second-year standout led the team in targets, but similar issues could be present in Arrowhead the following week as Los Angeles takes on a Kansas City team trying to keep its playoff hopes alive.
