The NFL says it is conducting a comprehensive review of allegations that Broncos quarterback Peyton Manning had human growth hormone delivered to his house.

There's no timetable to complete the investigation, but it's not expected before Denver plays Carolina in the Super Bowl on Feb. 7.

League spokesman Brian McCarthy says the inquiry, which began weeks ago, involves reviews of records, interviews and coordination with other agencies.

Al Jazeera reported last month that an intern at an Indianapolis anti-aging clinic was secretly recorded suggesting that Manning's wife received deliveries of HGH, which is banned by the league. Manning, then with the Colts, was rehabbing from shoulder surgeries.

The intern, Charles Sly, has since recanted his story.

Manning angrily denied using performance-enhancing substances and called the report "complete garbage."

Jet avoids jail

Jets defensive lineman Sheldon Richardson avoided jail time after pleading guilty to reduced charges connected to a high-speed police chase in suburban St. Louis.

A St. Charles County judge sentenced the former University of Missouri star to two years of probation and community service after his July arrest for driving a 2014 Bentley Silver Spur at speeds up to 143 mph on an interstate highway near his offseason home. The five misdemeanor charges included one for resisting arrest, for which Richardson could have spent up to one year in jail.

Richardson was accompanied by a 12-year-old relative and two male passengers when he was stopped.

Police say they found a loaded semiautomatic handgun under a floor mat and detected a strong marijuana odor.

Police defend decision

Police Chief Steve Mylett defended his department's investigation into a car crash involving Seahawks fullback Derrick Coleman, saying that his confidence level is "rock solid" in the investigation and charging recommendations.

Mylett spoke a day after the police report in Coleman's case was released and said he was particularly irritated by comments from Coleman's attorney, Steve Hayne. Mylett said he understands the attorney is attempting to defend his client but crossed a line when he attacked the integrity of the police department and the investigation.

Hayne said the 101-page report was intended to make Coleman look bad.

Police have recommended charges of vehicular assault and hit-and-run against Coleman and forwarded the case to the prosecutor's office.

Coleman was arrested Oct. 14 after a crash that left the driver of the other vehicle with a broken collarbone and a concussion, but the investigation only wrapped up last weekend. That led to some speculation that Bellevue police were waiting for the conclusion of the Seahawks' season before advancing the investigation.

Mylett rebuffed that speculation, saying toxicology reports and an analysis of the accident were only recently completed.

"There was no manipulation of timing when filing the charges. We filed it as soon as we were able to present a complete case to the prosecutor's office," Mylett said.

Etc.

Giants placekicker Josh Brown and cornerback Dominique Rodgers-Cromartie, Bengals cornerback Adam "Pacman" Jones and special teamer Cedric Peerman were added to the Pro Bowl roster.
