Buffalo coach Rex Ryan said his QB competition remains open, and he will not name a starter until just before the season opener against Indianapolis. He doesn't want to give the Colts any edge.
"We don't need to tell them," he said. "Until the league makes us tell them we can go right up there and say we're not going to say anything. We may know. But why would we say any different?"
After Manuel's TD pass and conversion, Manziel had one last chance, but he couldn't pull off any magic as the Browns (0-2) dropped their second straight preseason game at home.
Manziel connected with rookie Shane Wynn on a 21-yard TD pass in the fourth quarter. Playing against Buffalo's backups, Manziel finished 10 of 18 for 118 yards and made one of those Johnny Football plays -- rolling left and completing a 37-yard pass -- that made him an electrifying college star.
Following the game, Browns coach Mike Pettine reiterated that McCown, who threw interceptions on Cleveland's first two drives, was firmly the No. 1.
"We'll evaluate both guys," Pettine said. "I'm not going to sit here and talk about trying to start up a quarterback controversy."
Manziel said he's happy to be on the field and he'll leave the number of snaps up to Pettine.
"Would I like to be in there with the ones? Sure," he said. "It's not my call, and if that decision does come, I'll be ready to hop in there. But for now, I'm making the most of the opportunities I'm getting."
McCown did nothing to lock up the starting gig. He has not been named Cleveland's Week 1 starter, and Manziel's performance could further delay any decision.
"The things that stopped us were my mistakes," said McCown, who went 7 of 10 for 57 yards and two interceptions.
Following the game, McCown underwent X-rays on his right ring finger. McCown said initial tests were negative, but that he may need more.
