In the first three weeks, Johnson had caught seven passes in each of the first three games for at least 90 yards per game and had two touchdown catches. However, just as running back Arian Foster had returned from a hamstring injury, Johnson suffered one of his own in Week 4 against the Pittsburgh Steelers. In the second quarter, as Johnson caught a pass from Matt Schaub, he went down untouched, grabbing his right hamstring. The injury caused him to miss nine games and playing limited snaps in the other three. Johnson finished the season with career-lows in games played (7), receptions (33), yards (492), and touchdowns (2), but the Texans, in their tenth season in the NFL, made the playoffs for the first time in franchise history by winning the AFC South Division with a 10–6 record.
