Johnny Manziel’s rookie season is over, and the Cleveland Browns will prepare Connor Shaw to be the starter if Brian Hoyer cannot play.

Manziel suffered a hamstring injury in Cleveland’s 17-13 loss to the Carolina Panthers on Sunday, and coach Mike Pettine said Monday that the injury would have sidelined the quarterback for several weeks if the Browns were still playing beyond this week. The Browns (7-8) finish their season at Baltimore on Sunday.

Hoyer replaced Manziel against Carolina but suffered a shoulder injury and will be evaluated throughout the week, Pettine said.

“I just know he’s very sore today,” Pettine said. “Time’s going to heal it, but will it quiet down enough for him to be available Sunday?”

Shaw, a rookie who has spent the season on the practice squad, is expected to get first-team reps to prepare him for the start, and Pettine said the team is considering other quarterback options if it has to sign a player.

Manziel, Cleveland’s first-round pick earlier this year, played in five games, with two starts, and completed 51.4 percent of his passes (18 of 35) for 175 yards, no touchdowns and two interceptions. He had a 42.0 passer rating. He also ran nine times for 29 yards and a touchdown.
