Arian Foster tweets assurance he's fine

We hear irregular heartbeat and can't help but think it's serious and worry.

Houston running back Arian Foster and coach Gary Kubiak both said that Foster's issue during Sunday's loss to Minnesota was not a big deal.

Foster tweeted this morning that he's been to a specialist and checked out fine.

He'll be part of the Texans' efforts to get things right Sunday in their season finale in Indianapolis, when Houston can still clinch the No. 1 seed in the AFC.

Kansas City just ran wild on the Colts, so Foster should be a big part of the plan.
