Passage: The Titans pulled off an important divisional win behind the strong running of rookie RB Chris Johnson, who rushed for 93 yards in his NFL debut, and the arm of backup quarterback Kerry Collins, who replaced starter Vince Young when he went down late in the 4th quarter. Young had been inconsistent, throwing 1 TD pass to Johnson and 2 INTs. However, Collins moved the ball down field effectively and that drive led to the eventual game-winning touchdown run by LenDale White. Jacksonville trailed for much of the game and couldn't run the ball against a locked in Titans defense, who sacked Jaguars quarterback David Garrard 7 times. Both teams' defenses played well but the Titans held on. This game was also significant because the Jaguars, Texans, and Colts (in their debut at Lucas Oil Stadium) lost, so the Titans grabbed first place in the AFC South for the first week of the season, ending a 56-week streak of holding 1st place in the division by the Colts as the team started the season 1-0.
Question: How many NFL games did Chris Johnson play before this one?
