FOXBORO -- Calvin Johnson did not play in the Detroit Lions' second preseason game last Thursday because of a knee contusion.
Lions coach Jim Schwartz said it was a precautionary move to sit his star wideout.
Still, the Patriots will prepare for Thursday's preseason game in Detroit, as if Johnson will be their top wide receiver.
"This is definitely one of those run and gun teams that can put points on the board in a hurry," said New England cornerback Kyle Arrington after Tuesday's practice. "So we definitely want to start out fast, and just try to get as many guys to the ball as possible."
The Patriots' secondary has already had to deal with Philadelphia's DeSean Jackson and Tampa Bay's Vincent Jackson. If Johnson plays, they'll see one of the best wide receivers in the game.
At least, that's who they're preparing for.
"They don't make it easy, do they? No, not at all," said Arrington. "He's definitely the, shoot, you really have to know where he is at all times on the field. He's one of those guys where he just, you know, speed, quickness, hands, length. So he's the ultimate matchup. So it's definitely going to be a good challenge for us this Thursday."
