The decision came down following practice Wednesday night. Kevin Kolb will start at quarterback when the Bills host the Vikings Friday night in the preseason home opener.
"I'm looking for him to play. Play football. I just wanted to make sure he was healthy. I asked him if he was healthy and it was like, here we go. It's a competition and we just wanted it to be equal and again, I said, EJ this is not a reflection on you, as a matter of fact it's the opposite, actually you played really well for a guy making his first NFL start," Marrone said.
"Obviously, it picks up as we go from here, and I just think like I told you guys before you can't focus on that stuff you have to focus on playing quarterback and how do it get better and you have to be coachable and that's a big thing for Nate (Hackett) and our offense and that's what I'm out here to prove," Kolb said.
A welcome sight Wednesday night: Stevie Johnson back on the field catching balls during individual drills for the first time since injury his hamstring a few weeks ago.
"It feels good actually to be out there. It's not where I want it to be. I was hoping I could get more involved in practice but you know it is still pulling a little bit but every day it is getting better. You know, I've been working with the strength trainers and coaches to get right and hopefully I'll be back for Washington," Johnson said.
The Bills have a closed workout Thursday leading up to Friday's game with the Vikings.
