The Cincinnati Bengals placed three players on injured reserve Friday.
Boyd, who took over the No. 1 role at wide receiver after A.J. Green was injured earlier this season, finished with career highs across the board in his third NFL campaign.
A second-round draft pick out of Pittsburgh in 2016, Boyd notched 76 receptions for 1,028 yards and seven touchdowns in 14 games. He had 76 catches and three TDs in his first two seasons combined.
The 6-foot-2, 203-pound Boyd was hurt in a 30-16 win over the Oakland Raiders on Dec. 16. The injury reportedly was a low grade sprain of the medial collateral ligament.
Kirkpatrick, who injured his shoulder in last week's game against Cleveland, had 41 tackles and nine passes defensed in his seventh season since Cincinnati drafted him in the first round in 2012.
An ankle injury sidelined Jordan for the last three games of the season. The second-year linebacker registered 59 tackles, 1.5 sacks and one interception in 14 games.
In corresponding roster moves, Cincinnati promoted running back Quinton Flowers, offensive tackle Kent Perkins and wide receiver Hunter Sharp from the team's practice squad.
