Grimes carried the ball five times for 28 yards, caught both of his targets for 11 yards, and scored a two-point conversion in Sunday's 30-21 loss to Buffalo.
He's been getting between seven and eight touches per game in the last four weeks, as the Texans have relied on a committee approach to replace Arian Foster's production. Grimes would be a real gamble to put in a fantasy team's starting lineup.
