Week ten featured the Bears attempting to avoid suffering the first sweep by the Lions since 2007, while also trying to claim the division lead; the last time the two teams faced each other in a late-season game for the division lead was in 1991, which ended in a Chicago 20-10 win. However, the Bears had won the last five games against the Lions at Soldier Field. On November 7, Marc Trestman announced that Jay Cutler has been cleared by doctors to return against Detroit, despite having been projected to be out for approximately four weeks. Against the Lions, Cutler was 7-2, and won all four home games. On the offensive side, Jeff Joniak states that the Lions defensive line "are ferocious up the middle, they are physical, and they make you pay for poor technique," but that "there is growing confidence that the Bears offense is a resilient one;" the Bears had the fewest pre-snap penalties in the league, and only one false start. The Bears could also seize the Lions' cornerback corps, which struggled during the season, allowing 11 plays of 40 yards or more, along with 4.7 yards per carry. Defensively, Sports Illustrated writers Chris Burke and Doug Farrar wrote the Bears must attempt to hinder Reggie Bush, and improve their performance from the previous week, when the Packers' running game ran for 190 yards and two touchdowns. The Bears also had to prevent Calvin Johnson from excelling; against the Dallas Cowboys, Johnson recorded 329 receiving yards. Chicago scored first after Cutler's 32-yard touchdown pass to Brandon Marshall capped a 65-yard drive that took just 2:23. However, the Lions would travel 85 yards to tie on Matthew Stafford's 5-yard pass to Kris Durham. In the following quarter, the Bears reached the Lions' 4-yard line, but Cutler's pass was tipped by Ndamukong Suh, and intercepted by DeAndre Levy in the endzone; both teams would fail to score in the quarter. During the quarter, Cutler began showing signs of struggling due to an ankle injury. In the third quarter, the Lions would score on Stafford's four-yard touchdown to Johnson. Afterwards, the Bears were forced to settle for a 25-yard field goal, narrowing the gap to one point. In the fourth, Stafford was intercepted by Chris Conte, who reached Detroit's 9-yard line, and Cutler would then throw a 14-yard touchdown pass to Alshon Jeffery, which was eventually nullified. After an incomplete pass, Gould kicked a 32-yard field goal to draw the score to 14-13. However, Johnson would catch a 14-yard pass from Stafford to increase the lead to 21-13, and with 2:22 remaining, Josh McCown entered the game in favor of Cutler, and guided the Bears' offense 74 yards, culminating in McCown's 11-yard touchdown pass to Marshall with 40 seconds to go. On the two-point conversion, McCown's pass to tight end Dante Rosario fell incomplete, but Willie Young was penalized for roughing the passer, allowing the Bears a second chance, which failed after Matt Fort&#233; was tackled by Nick Fairley in the backfield. The Bears' onside kick would backfire, as Joique Bell recovered, sealing a season sweep for the Lions. Despite stating he was "100 percent" healthy after the groin injury suffered two games prior, it appeared the injury was still lingering; after throwing a pass during the third quarter, Cutler fell down and grabbed his groin, before standing back up.  Regarding the injuries, Cutler stated, "It held up OK. It's all on the same leg so I think that was a problem. But the groin, you take the ankle out of the equation and I would have been fine, I think." Cutler ended the game having completed 21 of 40 passes for 250 yards with a touchdown, interception and a 69.8 passer rating. Despite x-rays on his ankle being negative, Cutler was ruled out of the next week's game against the Baltimore Ravens with a high ankle sprain. During the second quarter, Charles Tillman was also injured, suffering a torn right triceps brachii muscle, and was placed on injured reserve with the designation to return, allowing him to practice after six weeks and play in games two weeks after; as a result, Tillman missed the entire regular season.
