Sports briefs: NCAA wants to slow up-tempo football

COLLEGE FOOTBALL • A proposed change by the NCAA rules committee would prohibit offenses from snapping the ball until at least 10 seconds had run off the 40-second play clock, slowing down the up-tempo, no-huddle attacks that have been making defenses dizzy.

The rule would give defenses time to make a substitution without the offense changing players — as is currently required — and with no fear the ball will be snapped before 29 seconds are left on the play clock. An exception would be made for the final two minutes of each half, when the offense could snap the ball as quickly as it wanted.

Elway gets extension

NFL • The Denver Broncos have extended Executive Vice President John Elway's contract for three years and added general manager to his title. The Broncos have gone 37-17 since Elway rejoined the team in 2011 and are coming off an AFC Championship but a 43-8 blowout to Seattle in the Super Bowl.

• Gregg Williams is returning to the Rams as defensive coordinator, the first time he will lead a defense since he lost his job in New Orleans amid the fallout from the team's bounty scandal. The Rams announced the hiring Wednesday and a news conference introducing Williams was scheduled for Thursday. He will replace Tim Walton, who was fired in January after just one season.
