Philip Rivers struggled in the Indianapolis Colts' loss to the Cleveland Browns on Sunday, but Frank Reich remains confident in his quarterback.

Rivers had an interception returned for a touchdown, another pick and an intentional grounding penalty that resulted in a safety for the Browns.

"Philip is playing really good football," Reich said. "That is the least of my worries. That is the least of my worries. Philip is playing good football. You are going to have mistakes when you get in situations like that. I know we would want the interception back, but the safety, like I said, is on me. You take that away and you get that one mistake, in my mind, that was the big factor. [The safety] was not the big factor, but the one big mistake with Philip was the interception. That is it."

Rivers played largely mistake-free football during the Colts' three-game winning streak which ended in Cleveland.
