Tailback Ryan Grant said Thursday he thinks he has picked up the Washington Redskins’ offense sufficiently to be ready to play when needed.

“I feel good,” Grant said. “I’ve been coming along. I feel like I’m picking it up just fine. Football is football. It’s just the terminology, really. There are not too many things that they do differently.”

The Redskins signed Grant, a former 1,200-yard rusher for the Green Bay Packers, last week when they placed running back Roy Helu on the injured reserve list.

But Grant was on the inactive list for last Sunday’s victory at Tampa while Evan Royster received some playing time behind the team’s rookie starter at tailback, Alfred Morris.

“The biggest thing with any back when they come in is the [pass] protection aspect, just making sure you’re on the same page,” Grant said. “That takes some communication…. I feel comfortable. I’d feel comfortable this week, next week, whatever we do.”
