After making considerable progress in stopping teams on third down in recent games, the Browns regressed against the Bears on Sunday.

The Bears were 9-of-14 converting third downs on Sunday for a whopping 64.3 percent. In the all-important fourth quarter when the Browns gave up three touchdowns, the Bears were 4-of-4 on third down. In fact, two of the Bears' touchdowns came on third down. The Browns were outscored 21-7 in the final period and have been outscored 128-66 in the fourth quarter for the season.

"It wasn't good enough," coach Rob Chudzinski said in a conference call Monday. "As you know, I felt that we had made some improvements through the course of the last number of weeks, but it has been too inconsistent.

"We had some busted coverage issues early in the game," he said. "Obviously, we gave up too many big plays on third down and we struggled, at times, with some of the matchups that Chicago presented us (with)."

Prior to Sunday's loss to the Bears, the Browns had held their opponents to 33.3 percent in the five previous games. On the season, the Browns have allowed their opponents to convert 92-of-214 third down attempts for 43 percent.

On the Bears first scoring drive, they were three-of-four on third down, including conversions on third-and-8 and third-and-11. The lone stop resulted in Chicago settling for a field goal.

On the first of three fourth-quarter touchdowns, the Bears were two-of-two on third down, including a 45-yard touchdown to Alshon Jeffery on third-and-11. On the Bears' second touchdown of the fourth quarter, the only third down was the touchdown pass to Earl Bennett on third-and-4 from the four-yard line. Finally, on the Bears' final touchdown drive, they converted the only third down as Matt Forte ran for 24 yards on third-and-9.
