Cleveland Browns right tackle Jack Conklin is set to undergo surgery after suffering a season-ending right knee injury on Sunday night during the game against Baltimore Ravens.

While blocking a pass in the first quarter against the Ravens, who held the Browns to a season-low 40 yards rushing, Conklin ruptured his patellar tendon. An MRI taken Monday confirmed the diagnosis of a tear.

Coach Kevin Stefanski said he was “sick” over Conklin’s injury, the Associated Press reported. “Obviously, Jack’s a big part of what we do,” Stefanski said Monday. “He’s a good man, good teammate.”

Cleveland’s offence, which has scored 17 points or fewer in six of its last seven games, will be further hampered by Conklin’s injury.

Conklin, a two-time All-Pro, returned to the lineup on Saturday after missing three games due to a dislocated elbow. During the Browns’ second possession against the Ravens, Conklin’s leg buckled as he back-pedalled, and he fought to walk to the sideline before being carried to the locker room.

Due to a knee ailment, Conklin missed two games earlier this season.

Stefanski stated that the tight end is In the 16-10 defeat, Harrison Bryant suffered a high ankle sprain. He also stated that running back Kareem Hunt, who was forced to leave the game late due to a calf strain, should be OK.

Hunt has just recently returned to the lineup after missing five games due to a calf injury.

The Browns’ high-powered rushing attack stuttered without Conklin, as the Ravens jammed the line of scrimmage with extra defenders and reduced Cleveland to 116 yards below its pre-game average.

Backup Blake Hance replaced Conklin on Sunday night and filled in for him earlier this year. Hance has had some issues at tackle after playing mostly guard.

The Browns have their bye this week before hosting the AFC North-leading Ravens on Dec. 12.

Cleveland also placed long snapper Charley Hughlett and practice squad fullback Johnny Stanton on the COVID-19 reserve list.
