Browns right tackle Jack Conklin out for season with torn ACL, MCL

Browns right tackle Jack Conklin tore his ACL and MCL and will miss rest of season.
Rookie Dawand Jones will replace Conklin at right tackle and make first career start.
Conklin received a four-year contract extension from the Browns in December.
Browns will need Jones to develop quickly to improve offensive line without Conklin.
Conklin has battled injuries during time with Browns and previously with Titans.
