DETROIT - The only person Lions wide receiver Roy Williams exploited Sunday was himself.
The talented and talkative Williams had joked during the week that if Bears cornerback Charles Tillman didn't play then he would "just have to exploit" another Bears corner.
But Tillman did play, and he and Corey Graham, filling in for injured Nate Vasher, kept the Lions' passing game under wraps.
Williams caught 7 passes for 96 yards, but he dropped at least 5 catchable passes.
"That's how it goes," Graham said. "I just wanted to go out there and be confident and try to make some plays. I didn't get too much (action) out there, but I thought that when I did I did very well."
Johnson, who came in leading the Lions with 17 catches for 276 yards in just three games, was held to 2 catches for 16 yards. Graham was second on the Bears with 7 tackles, unofficially, and Tillman broke up 4 passes and returned an interception 26 yards for a TD.
Get serious: Safety Mike Brown may have given Lions wide receiver Roy Williams a pat on the rear end near the end of the Bears' blowout victory, but he wasn't feeling any sympathy for the woebegone Lions or their yappy pass catcher.
"Are you kidding me?" Brown replied when asked by a member of the Lions' media if he felt sorry for the Lions. "There's no pity for the Lions. We don't have pity for the Lions. They don't have pity for us either when they were kicking our butts last year. What are you talking about?"
The Lions beat the Bears 37-27 and 16-7 last season.
No mercy rule: Bears coach Lovie Smith and Lions coach Rod Marinelli were assistants together in Tampa Bay for five years, but Smith said there's no such thing as mercy for an opponent in the NFL, even for a friend.
"Rod Marinelli isn't looking for any mercy," Smith said. "He's a heck of a football coach. They had a tough day today. Believe me, he'll get the troops back."
Smith cannot be accused of letting up on Marinelli. Leading 34-7 with eight minutes left in the game, Bears quarterback Kyle Orton went deep for a 19-yard completion to Rashied Davis, and three plays later went deeper yet on a pass intended for Devin Hester that was incomplete.
Triumphant return: Against his former team, running back Kevin Jones contributed 36 yards on 10 carries in his most extended playing time since the season opener.
"It felt good," said Jones, who was released after four seasons in Detroit. "I got to run the ball a little bit. I was just trying to get in a rhythm and just keep pounding them. That's what I tried to do today."
Jones was booed mildly by the Lions' fans, most of whom were more involved booing the home team.
"I thought they was booing the Lions, not me," Jones said with a laugh. "There were a lot of Bears fans cheering, so that's what I heard the most."
Jones had a 16-yard run on the final play of the third quarter that was almost a lot longer.
"Oh man, it was close," he said. "They got my ankle."
Injuries, lies, inactives: Cornerback Nate Vasher, who said after Friday's practice: "I expect to be out there 100 percent," was 100 percent inactive on Sunday.
Vasher suffered a dislocated thumb in Week 4 but finished the game and then had a minor surgical procedure, but he returned to the practice field Friday after sitting out Wednesday and Thursday.
Corey Graham started in place of Vasher, as he had done in Week 3 when the Bears preferred going with a bigger more physical lineup.
The Bears' other inactives are wide receiver Brandon Lloyd (knee), defensive tackle Matt Toeaina, offensive tackle Chris Williams, guard Dan Buenning, safety Craig Steltz and quarterback Caleb Hanie.
Tommie Harris was suspended for Sunday's game because of repeated tardiness.
Linebacker Nick Roach suffered a shoulder injury in the third quarter and did not return.
