Trent Richardson wanted more work in Cleveland. He’s about to get his wish in Indianapolis.

Less than two weeks after being traded from the Browns, the 2012 first-round draft pick will be given more carries and a bigger role Sunday after starter Ahmad Bradshaw was ruled out with a neck injury.

Richardson, who has been studying his playbook relentlessly, said he’s ready.

“I’ve been learning the game plan every day and sticking my face in that playbook two hours after practice, an hour before practice, at the meetings and stuff,” Richardson said. “I’ve been studying hard so I feel like that workload, I’m ready to go for it.”

The Colts (2-1) don’t have much choice.

Their original starter, Vick Ballard, went down with a season-ending knee injury before Indy’s second game. Bradshaw started in a loss to Miami and again last week against San Francisco, four days after the Colts sent a 2014 first-round pick to Cleveland for Richardson.

Bradshaw responded with his best game since joining the Colts in June, rushing 19 times for 95 yards and a late touchdown.

But he took a big shot early in the game. Initially, he tried to get up before falling to his knees.

Vikings to start Cassel

Matt Cassel will get a chance to steer the Minnesota Vikings to their first win of the season — and maybe put himself in position for a more regular role. Cassel will replace injured starter Christian Ponder at quarterback against the Pittsburgh Steelers on Sunday at Wembley Stadium. The Vikings (0-3) ruled out Ponder on Friday with a fractured rib.

“We worked with Matt in the mindset that this was a possibility, so I think we’re prepared in that way,” coach Leslie Frazier said.

Cassel hasn’t played a down this season since signing a two-year deal with the Vikings in the offseason.

The former New England Patriot threw six touchdowns and 12 interceptions in nine games for the 2-14 Chiefs last season.

Seattle’s line hurting

The Seattle Seahawks could be missing three starting offensive linemen when they take the field against the Houston Texans on Sunday. Right tackle Breno Giacomini and center Max Unger are both listed as doubtful to play against the league’s second-ranked defense. Unger has a triceps injury suffered last week against the Jacksonville Jaguars. Giacomini is dealing with a sore knee that worsened last week against the Jaguars. Left tackle Russell Okung is also out after being placed on the short-term injured reserve list last week with a sprained toe ligament in his left foot.
