Johnston caught all four of his targets for 37 yards in Sunday's 24-9 loss to the Rams.
Johnston's four grabs marked a new personal single-game high through six games this season. One of the least efficient wideouts in the league, Johnston entered Sunday with just eight grabs for 165 yards on 22 targets. He hasn't been playable in fantasy football for weeks and will square off with a stingy Houston secondary in Week 9.
