ENGLEWOOD, Colo. (AP) — Ronnie Hillman and Montee Ball stood out for all the wrong reasons last weekend.

Denver’s young running backs want to atone for their big blunders when the Broncos host the St. Louis Rams on Saturday night in what’s essentially the final dress rehearsal for the regular season.

Hillman fumbled when he tried to stretch the ball over the goal line on second down from the 1, and Seattle cornerback Brandon Browner returned it 106 yards for a touchdown that set the tone for the 40-10 thumping by the Seahawks.

Ball whiffed on a Seahawks blitzer and allowed Peyton Manning to get creamed.

One gaffe cost them a touchdown; the other could have cost them the season.
