Harris has been able to contain Williams in their meetings over the years. In Williams' rookie year with the Lions, he was held to just one catch with Harris as the primary defender. In 2005, Harris broke up a pass intended for Williams in the end zone.
But in 2006, Williams had a seven-catch, 138-yard performance -- one TD -- while being covered by Harris. It was the fourth-best receiving-yards day in Williams' career.
That same season, Harris intercepted a pass intended for Williams which set up a game-tying field goal.
And they'll meet again Sunday.
"Al is a shut-down corner -- one of the best in the game in my opinion," said Williams, who has 21 catches for 308 yards with two touchdowns in seven career games vs. the Packers. "A guy who can play one-on-one. We have to work to defeat those guys and we'll see what happens."
The emergence of Miles Austin, who has six touchdown catches the last four weeks, could have Harris guarding him instead of Williams. Green Bay likes to play man-to-man defense with its corners, and sometimes they jam receivers at the line of scrimmage
"It makes me excited," Williams said of Harris. "We've had battles for five years now, going back to my Detroit days. He knows me. I know him. May the best man win.
"Al usually travels with me, probably not this time."
