Denver Broncos offensive coordinator Adam Gase has said that the team need to reduce the number of fumbles that they make.
The AFC West side had three fumbles during the first half of their 40-10 defeat to the Seattle Seahawks last week.
Gase told the team's website: "[Fumbles have] been a huge point of emphasis for us this off-season because the fumbles we had early in the season last year, that was one of the main factors of why we started off as slowly as we did.
"Right now, the guys we have running the ball are the guys we have running the ball, and their job is to make sure they hold onto the ball, and that's what they're going to do.
"The ball security, when the ball is in your hand, the ball cannot be on the ground. What happened the other day? I'm telling you, unacceptable. It's not going to happen. It's not going to happen anymore. We're not going to put the ball on the ground, or else they're not going to carry it."
The Broncos face the St Louis Rams on Saturday.
