The Cleveland Browns released their Week 6 injury report on Friday, and linebacker D'Qwell Jackson (concussion) is among the players listed as probable, and DT Ahtyba Rubin (calf) is listed as questionable.
Cleveland's defense will Joe Haden back from suspension this week, so if Jackson sees the field the unit may improve quickly. The defense is currently ranked No. 25 against the pass and No. 27 against the run, while their mark of 27.8 points allowed per game puts them at No. 25 in the NFL.
The Browns host the Bengals in Week 6. They lost the previous meeting in Week 2 by a score of 34-27.
Jackson left Sunday's game in the second quarter after taking a blow to the head. He was later diagnosed with a concussion which meant he had to pass NFL mandated tests before he would be allowed to return to the field. After missing practice on Wednesday, Jackson apparently passed the tests as he was back on the practice field on Thursday.
His return is a huge boost for the Browns defense. Jackson has started all five games this season and has done a little bit of everything for Cleveland. He is second on the team with 31 total tackles, but leads the Browns in both sacks and interceptions. Jackson has 3.0 sacks already this season, just half-a-sack shy of his career-high.
The Browns rush defense struggled when Jackson left the game, so his return should help as they prepare to face the Bengals on Sunday.
Per his usual policy, Browns coach Pat Shurmur didn't discuss injuries in his Wednesday press conference. He said Jackson was "in the building and all the meetings today" but chose to say "we'll see" when asked if Jackson would be at practice.
Jackson suffered a concussion during Sunday's loss to the New York Giants. Jackson will have to pass multiple concussion tests in order to play in Sunday's game against the Bengals.
Jackson was drafted by the Browns in the second round of the 2006 NFL Draft. Jackson missed most of the 2009 season, then missed the entire 2010 season with a torn pectoral muscle.
Through Cleveland's first five games this year, Jackson has registered 31 tackles, and has recorded three sacks. Jackson also has two interceptions and a fumble recovery.
The Browns' defensive leader left the game with a couple of minutes to play in the first half with what was reported to be a head injury. Rookie L.J. Fort replaced Jackson, and by the day's end led the team with 10 tackles. Jackson had five tackles before he went to the locker room.
The loss of Jackson came in the midst of the Giants scoring off two Cleveland turnovers. New York scored three times in the final three minutes of the first half to dissolve the Browns' 17-10 lead and take control of the game.
Jackson has not had concussion problems in the past. He did, however, miss 26 games in 2009 and 2010 because of two pectoral muscle injuries.
