CLEVELAND (AP) — Browns right tackle Jack Conklin will undergo surgery after suffering a season-ending knee injury Sunday night at Baltimore. His loss is a crushing blow to a Cleveland offense struggling to score. Conklin ruptured his patellar tendon while pass blocking in the first quarter against the Ravens, who held the Browns to a season-low 40 yards rushing. Coach Kevin Stefanski said he was “sick” over Conklin’s injury. A two-time Pro Bowler, Conklin was only activated from injured reserve Saturday after missing three games with a dislocated elbow.
