Thad Lewis has said that he has "no nerves" ahead of his first start for the Buffalo Bills this weekend.
The quarterback was promoted from the team's practice squad when EJ Manuel was ruled out for several weeks with a knee injury.
The 25-year-old told reporters: "No nerves at all. I've done it before but I'm still playing football, it's not like anything changed. I'm doing the same thing I was doing, I am just able to play this Sunday.
"It's easy when you practise now, I've already came in three days ahead along with the pre-season and just had to play and didn't get any full speed reps, it will be difficult. With three days of practice you pretty much get the time in with the guys and today we had a good day.
"If you second guess yourself, those guys will take advantage of that. So going into the game, definitely going to be confident. Being home definitely plays a part, the crowd will be on my side this time so I'm looking forward to that."
The Bills play the Cincinnati Bengals in the NFL this weekend.
