INDIANAPOLIS — Former Iowa quarterback Jake Rudock showed the Detroit Lions he could fill in for Matthew Stafford — if needed.

The Indianapolis Colts, meanwhile, are still looking for an answer behind Andrew Luck.

Rudock took advantage of the injury-depleted Colts by throwing two touchdown passes to Kenny Golladay, driving the Lions to a short field goal and leading them to a 24-10 victory in the preseason opener on Sunday.

“You can see the difference between last year and this year at this time,” Lions Coach Jim Caldwell said. “He has a better grasp of things around him. He’s in command.”

The second-year quarterback, who finished his college career at Michigan, played most of the first 2½ quarters and wound up 13-of-21 for 142 yards. Stafford played one series, going 2-of-3 for 36 yards and left after throwing an interception.

Jaguars lose receiver Lee

JACKSONVILLE, Fla. — Jaguars receiver Marqise Lee was carted off the field Sunday with a right leg injury, a potentially significant setback for a team already without rookie running back Leonard Fournette, who has been bothered by a foot injury.

Lee fell to the ground during seven-on-seven drills and immediately grabbed his leg. Linebacker Telvin Smith called for trainers.

Lee’s lower leg was immobilized before he was taken off the field on a cart.

Johnson sees little action

GLENDALE, Ariz. — Clinton’s David Johnson saw limited action in Arizona’s 20-10 preseason win against Oakland on Saturday night.

Johnson carried the ball three times for 16 yards in the Cardinals’ second preseason game of the year.
