The Colts rallied from a 14-point deficit in the second half to knock off the Browns, 25-24.  The defense got off to a fast start right away and dominated for 59 minutes, forcing 4 turnovers in the contest. QB Andrew Luck fumbled on the Colts' 1 yard line, and the ball was recovered in the endzone to make it 7-0.  With a chance to go up 10-0, Browns K Billy Cundiff missed a 40 yd. field goal that would later prove to be very costly.  Following the miss, Luck rushed for a TD to tie the game at 7-7.  On the next drive, Hoyer led the Browns downfield; Rookie RB Isaiah Crowell ran in for a touchdown to lead 14-7 at halftime. In the second half, the Colts' turnover problems continued, committing a fumble on their first drive that the Browns couldn't convert into points. Later in the quarter, Luck threw a "pick-six" to Browns rookie DB Justin Gilbert (his 1st INT of the year), and the Browns went up 21-7.  The next two Colts' drives resulted in points (a field goal and a T. Y. Hilton touchdown), cutting the deficit to 21-16 heading into the 4th quarter. Adding another FG in the 4th to make it 21-19, and with a chance to take the lead, Luck threw another interception (he was sacked 3 times). However, the Browns failed to get a first down and were forced to settle for 3, making it 24-19 Browns and leaving the door open for the Colts to take the lead. With less than 4 minutes to go, Luck led a 90-yard game-winning touchdown drive. The Browns had a chance to end the game with a stop on 4th and inches at the 3 yard line, but RB Dan Herron avoided the tackle and picked up 2 yards for a Colts first down. Luck would throw the game-winning TD pass to Hilton on the next play, making it 25-24 Colts with 36 seconds left. After a failed two point conversion, and with the Browns having one more chance to win the game, Hoyer threw his 2nd INT with less than 10 seconds remaining, and the Colts ran out the clock. The Browns' offense was barely noticeable throughout the contest. TE Jordan Cameron returned to duty after 5 weeks, leading all Browns receivers with only 41 yds. 17 of the teams' 24 points came off of Colts turnovers, the defense converting two into TD's.  Punt and kick coverage teams kept returning fan-favorite KR Joshua Cribbs in check, and traded RB Trent Richardson was held to 30 yds. on 7 carries. MLB D'Qwell Jackson had 9 tackles for Indy, but no sacks. In the second half, the Browns' offense failed to convert a single 3rd down (0/6).  For the fourth consecutive game, Hoyer was dismal, passing 14/31 for 140 yards, 0 TD's, and 2 INT's (the third straight game that Hoyer had 0 TD's and multiple INT's).  It was the second game in a row that the Browns failed to win after holding a halftime lead.  It was only the second time that the Browns lost when holding a 4th quarter lead at any point (the other loss coming to the Ravens in Week 3). After starting 6-3, the Browns are 1-3 in their last 4 games.  The Browns' offense scored 26 points in their one victory while all 3 losses featured the offense scoring 10 or fewer points. The Browns fell to 7-6 on the season; wins by the Steelers and Ravens would leave the Browns in sole possession of 4th place in the AFC North.  It was the first time this season that the Browns lost back-to-back games, and consecutive home games. The Browns also lost their ninth consecutive December game, a drought that goes back to Week 15 of the 2012 season.  A loss in Week 15 to the Bengals (8-4-1) would eliminate the Browns (7-6) from contention for the AFC North title and possibly the postseason. On Tuesday, it was announced that Johnny Manziel would start over the struggling Brian Hoyer. Starting G Ryan Seymour moved to center, replacing Nick McDonald as the team's 4th center to start a game. He is expected to finish the season at that position. K Billy Cundiff was released from the team on December 13, replaced by K Garrett Hartley.
