CINCINNATI - A.J. Green will miss his sixth straight game and Vontaze Burfict's status for Sunday's season finale is doubtful, the Bengals said.
The Bengals put Green (hamstring), tackle Cedric Ogbuehi (shouder), tight end Tyler Eifert (back injury) and guard Clint Boling (shoulder) on injured reserve this week.
Green missed the last five games with a strained hamstring, and yet he was just 36 yards from joining Randy Moss as the only NFL players to top 1,000 yards receiving in each of their first six seasons. Green finished with 66 catches for 964 yards.
The team flew their star wide receiver to Houston for last week's game in anticipation of playing him but then had second thoughts.
Linebacker Burfict is still in concussion protocol and he will be reviewed, He also missed the Houston game.
The Bengals signed WR Jake Kumerow, LB Trevor Roachand HB Tra Carson from their practice squad to fill their roster.
The Bengals (5-9-1) host the Ravens (8-7) Sunday with both teams out of playoff contention.
Kumerow (6-4, 206; Wisconsin-Whitewater) has been activated for the first time after two seasons on the practice squad. He played in three 2016 preseason games with four receptions for 67 yards.
Roach (6-2, 247; Nebraska) played in Games 1-3 (no statistics) and was moved to the practice squad after Burfict finished his three-game suspension. Roach played in three 2016 preseason games with 13 tackles. He spent the 2015 regular season on the practice squad and made his NFL debut in the Wild Card playoff vs. Pittsburgh, logging one special teams tackle.
Carson (5-11, 231; Texas A&M) is in his rookie season. He played in all four Bengals preseason games, leading the team in rushing yards (85).
