The Lions scored an NFL-record 34 points in the fourth quarter as they overcame the Chicago Bears 37-27 Sunday. Jon Kitna threw two touchdown passes in the final quarter as the Lions broke the previous record by three points. Brian Griese, who had three interceptions as a starter in place of Rex Grossman, threw a 1-yard pass to Desmond Clark on a fourth down with 52 seconds left to pull the Bears within three. However, the onside kick bounced to Detroit's Casey FitzSimmons and he returned it for a TD to seal the victory.

Lions rookie wide receiver Calvin Johnson was listed as questionable for Sunday's home game against the Chicago Bears. Johnson scored in the first two games of the season, but suffered a back injury in last week's 56-21 loss in Philadelphia. The loss dropped Detroit to 2-1.

Wide receiver Calvin Johnson walked gingerly through the Lions' locker room Monday, like an old man. A teammate teased him, and he smiled. Johnson, the second overall pick in this year's draft, suffered a lower back injury when he fell making an impressive, leaping catch in Sunday's 56-21 loss at Philadelphia. But it's just a bad bruise. Nothing's broken. "Just came down wrong, I guess," Johnson said. "I smacked the dirt pretty hard. I felt it right away." Marinelli said Johnson was probably day-to-day

The Detroit Lions have placed starting tight end Dan Campbell, who sustained an elbow injury in last Sunday's overtime victory against the Minnesota Vikings, on injured reserve, ending his 2007 season. A ninth-year veteran, Campbell is regarded as one of the best, albeit underrated, blocking tight ends in the league, and the Detroit running game will suffer far more than the passing attack in his absence. Second-year player Sean McHugh will take over as the starter. The Lions elevated Rudy Sylvan, a rookie from Ohio University, from the practice squad to the active roster to fill Campbell's spot.

Lions quarterback Jon Kitna, who led the Lions to an overtime victory against the Vikings last week despite suffering a concussion in the first half, he expects Donovan McNabb to respond at the highest level. "This team (the Eagles) has always responded well to adversity," Kitna said. "It seems like the more adversity there is, the higher they respond. We know what type of place it is going to be. It is going to be a hornets' nest, and they are going to try to blow the drawers off."

The Lions offered guarded optimism Friday about the return of Kevin Jones, but several signs pointed to the hard-nosed, versatile running back making his season debut Sunday at Philadelphia. "I'm really optimistic. I'm excited," Lions coach Rod Marinelli said Friday. "I feel good about it. We'll wait and see. Each morning is a new adventure." A key concern for Jones' foot has been how much swelling occurs a day after practice. Marinelli said Jones was fine one day after a hard practice Thursday, when his formerly plain silver helmet was finally adorned with Lions decals. The team is scheduled to fly to Philadelphia today and Jones will wear a compression sock to limit any swelling incurred from the plane's pressurized cabin.

When Adrian Peterson visited Lions headquarters before the NFL draft, one thing stuck out. "The head coach, I felt like he was an awesome dude," Peterson said. "He was real cool. I really felt like I could have related to him a little bit as far as being a player's coach." Rod Marinelli thought Peterson was awesome, too. He loved the tape he had seen of the Fiesta Bowl -- Peterson sprinting downfield to make a tackle after an interception against Boise State. "The effort," Marinelli said. "To get up off the ground. That spoke volumes to me about the type of person he is and the type of player he is."

A 17-point lead quickly turned into a one-point deficit. The opposing crowd was roaring its approval. The kind of situation that would have doomed the Lions a year ago was easily overcome in the season opener. Jon Kitna backed up his big boasts by throwing a go-ahead, 32-yard touchdown pass to Shaun McDonald with 4:15 remaining, and Dewayne White caused two turnovers in the closing minutes to help the Lions spoil Lane Kiffin's coaching debut in Oakland with a 36-21 victory over the Raiders on Sunday.

The Kansas City Chiefs claimed linebacker Johnny Baldwin off waivers from Detroit on Tuesday. The Chiefs also added wide receiver Bobby Sippio to their practice squad.

The Lions unveiled their 53-man roster Saturday, but that doesn?t mean it?s set in stone. Lions officials spent Sunday evaluating players cut around the NFL, looking for potential upgrades, while putting together a practice squad. The Lions? backup quarterbacks ? J.T. O?Sullivan and Dan Orlovsky ? have 17 NFL throws combined, and Jacksonville cut veteran quarterback Byron Leftwich. Asked if the Lions were interested at all in Leftwich, coach Rod Marinelli said: ?We?re going to look at all these guys right now. We?re up actually right now watching tape on just about everybody that?s been released.?
