Cleveland Browns coach Mike Pettine has not made the announcement yet, but Johnny Manziel is expected to follow up his preseason debut as a backup by starting against the Washington Redskins next Monday night in FedEx Field.

During a conference call Sunday, Pettine said he has not settled on a starter for the Aug. 18 game. He also denied a report by ESPN's Bob Holtzman claiming a team source told him Manziel has moved ahead of Brian Hoyer in the quarterback competition.

"I'm not sure who his team source would be," Pettine said. "The people most involved in the decision are myself and (quarterbacks coach) Dowell Loggains and (offensive coordinator) Kyle Shanahan. It's something I'm not going to pay a lot of attention to. I don't like being in the business of anonymous sources.

"We put Brian out there with the ones, and that was for a reason. He was ahead because of the edge he had in experience and the lead he had with the playbook. He's done nothing to have that taken away from him, but Johnny has made a lot of improvement. It was him vs. the playbook and he's handling it well."

Manziel entered Saturday night's game against the Detroit Lions in Ford Field with 7:32 left in the second quarter after Hoyer led the offense to two field goals in three possessions.

Manziel and the second-team offense were on the field for four possessions, not counting a kneel-down for one play at the end of the first half, and had one field goal. Manziel rushed for 27 yards on six runs and completed 7 of 11 passes for 63 yards.
