After a strong performance during Sunday's preseason game against the Vikings, 49ers coach Jim Harbaugh tabbed Colt McCoy as the backup quarterback to starter Colin Kaepernick.

"I feel real good about Colt as the backup quarterback," Harbaugh said, per CSN Bay Area.

McCoy completed 11 of 15 passes for 109 yards. He did not have a touchdown and one interception, but McCoy is completing 60.7 percent of his passes (17 for 28) in three preseason games.

"Over the last week, I feel like things have come together," McCoy said Sunday. "I practiced really well. And, then, minus a couple exceptions, I felt I played well tonight. All that is confidence for me, moving forward. Was I ever scared or nervous? No, I wasn't worried about the situation. I was more concerned about me getting a grasp of what's going on. And I really think I'm on my way to a lot of improvement there."
