The continued poor production from running back Trent Richardson since his trade from Cleveland to the Colts before Week 3 is not the only mystery surrounding his season. Another is his lack of use in the passing game. But Chuck Pagano plans on changing that.

Richardson caught 51 passes for the Browns as a rookie in 2012, but only four since joining the Colts. His 24-yard catch-and-run off a screen Sunday in Houston helped set up the winning touchdown. That could be a portent of things to come.

"We know he's got that ability," Pagano told the Indianapolis Star. "I think as he gets more comfortable with the scheme and terminology and all those types of things and the game, the situation, the score, all those things kind of line up ... we'd love to get him in space more and get him the ball more."

Richardson, who is averaging just 3.0 YPC with Indianapolis, is also now dealing with an ankle injury that sidelined him from Wednesday and Thursday practices.
