The Denver Broncos are considering selling advertising space on players' practice jerseys.
Joe Ellis, the team's chief operating officer, says the ads are something the team is exploring as they get ready for the new season.
He also said the team is in negotiations with the Colorado Lottery to use the team's logo on lottery tickets.
The NFL recently relaxed its rules regarding deals between teams and state lotteries. Ellis says he's hopeful the Broncos can reach a partnership agreement with the Lottery.
