McConkey caught three of his six targets for 44 yards in the 20-10 loss to the Steelers on Sunday.
McConkey's longest reception, an 18-yarder in the fourth quarter, actually came from backup QB Taylor Heinicke, who took over in the final 15 minutes after Justin Herbert appeared to aggravate an ankle injury he had coming into the contest. The rookie now has at least two catches in all three games and is clearly viewed as one of the team's top targets, but with such a heavy emphasis on the running game, it's hard to imagine any Chargers pass catcher putting together an explosive fantasy day, especially if Heinicke is slated to play more in the future.
