Having been eliminated from postseason contention, the Browns entered this game playing for pride and looking to sweep the NFC South.  In a low scoring first half, the Panthers jumped out to a 10-3 lead. QB Johnny Manziel got off to another slow start, going 3 for 8 with only 32 passing yards.  The Browns gained only 2 first downs with Manziel in the first half (with one first down coming via penalty).  With less than two minutes remaining in the first half, Manziel injured his hamstring, and was ruled out for the rest of the game. In the third quarter, the Browns added a field goal from newly signed K Garrett Hartley, cutting the deficit to 10-6.  In the fourth quarter, Hoyer threw an 81-yard TD pass to TE Jordan Cameron, and the Browns led 13-10.  However, the Panthers would score the go-ahead touchdown on their next drive and go up 17-13.  With the Browns facing a 4th and 11 at midfield, HC Mike Pettine elected to punt.  The Browns' defense couldn't force a punt or turnover, and the Panthers ran out the clock. With the loss, the Browns lost their fourth straight game as their record dropped to 7-8 and guaranteed a finish in fourth place in the AFC North.  The Browns have lost 11 consecutive December games going back to Week 15 of the 2012 season.  The Browns have now gone seven consecutive seasons without a winning record.  Since the franchise returned to the NFL in 1999, the Browns have finished without a winning record 14 of the last 16 years. The AFC North division went 11 straight weeks with all teams having winning records, and 12 of 16 weeks above .500, best in the league since 2008. On December 23, Pro Bowl selections were announced for the season: DB's Tashaun Gipson and Joe Haden are on the starting roster, along with OT Joe Thomas, his 8th straight trip and the first offensive lineman in NFL history to be nominated in each of his first 8 seasons, passing the great Lou Groza and second only to the legendary Jim Brown for the team's all-time nomination record. On December 24, QB Johnny Manziel was placed on IR; practice squad QB Connor Shaw is taking first-team reps, and Tyler Thigpen was signed to a temporary contract. On December 26, due to injuries to both Hoyer and Manziel, Connor Shaw was announced to be the starting quarterback for the Browns' Week 17 matchup against the Ravens.  On December 27, Browns' WR Josh Gordon was suspended for the season finale for a violation of team rules. He will be the first player to lead the NFL in receiving and then fail to score a touchdown the following season since Raymond Berry in 1961.
