Denver Broncos kicker Matt Prater will be suspended for four games for violating the NFL substance-abuse policy, according to the Denver Post.

The suspension stems from an alcohol-related violating since Prater has been in the NFL alcohol program since being charged with driving under the influence in 2011.

The suspension is set to be announced Monday and Prater initially faced a one-year suspension.

"No one feels worse about this than Matt Prater," lawyer Harvey Steinberg said. "He feels terribly for his teammates. It's cost him personally, both professionally and financially. I wonder if we shouldn't take a second look at the policy when only a couple beers were consumed at home while he was on vacation. Having said that, the NFL under the constraints of the policy couldn't have treated us better."

Prater was apologetic about the suspension.

"I've made some mistakes," Prater said. "I'm accepting full responsibility. I'll learn from it and come back a better person. I want to apologize to my teammates, my coaches, the Broncos' organization and the fans."
