The Bears entered week 15 of the NFL season hoping to secure a first-round bye and home-field advantage throughout the NFC playoffs. The Bears led 24-3 with 5:22 left in the third quarter and were en route to winning their third straight. During the first quarter, the Bucs had only reached 80 yards in total offense. Coach Jon Gruden sent in back-up Tim Rattay, who completed 20 of 35 for 268 yards with 3 touchdowns and one interception as the Bucs battled back to tie the game up at 31 during the fourth quarter. A controversial move was made by Chicago Bears' head coach Lovie Smith as he decided to let time expire during the fourth quarter and thus send the game into overtime. Tampa Bay won the coin toss, and both teams had three possessions in overtime. After missing earlier in the overtime period, Robbie Gould connected on a 27-yard field goal with 3:37 remaining to give the Bears the victory, 34-31. This loss sent the struggling Buccaneers to 3-11 which secured last place in the NFC South standings.
