Cincinnati Bengals defensive end Michael Johnson is expected to be sidelined for "a few weeks," the NFL Network reported Friday.
Johnson suffered a knee injury in the first quarter of Thursday's 34-23 win over the visiting Baltimore Ravens and did not return.
The 6-foot-7, 280-pound Johnson was among the final cuts when Cincinnati trimmed its active roster to 53 players, but he was re-signed shortly afterward.
A member of the Bengals since he was selected in the third round of the 2009 NFL Draft, Johnson started at least 15 games in six of the past seven seasons.
Johnson had 49 tackles and 5.0 sacks in 2017, boosting his career total to 44.0 sacks in 140 games. Cincinnati has plenty of depth on the defensive line, including rookie Sam Hubbard along with Jordan Willis and Carl Lawson.
The Bengals also sustained an injury on the offensive line as rookie center Billy Price exited Thursday's game with a sprained ankle, according to the team's official website. No timetable was given for his expected absence.
Price, who tore a pectoral muscle as the NFL Combine, was selected in the first round (No. 21 overall) of the 2018 Draft. He started at guard for three seasons with Ohio State before shuffling to center in 2017.
The 6-foot-4, 305-pound Price was the 2017 Big Ten Rimington-Pace winner as the conference's top offensive lineman and Rimington Trophy winner as college football's top center. He finished his career with school records for both total and consecutive starts (55).
