Texans RB Foster injures calf at OTAs

Houston Texans running back Arian Foster spent most of Tuesday's organized team activity practice in the training room after suffering what coach Gary Kubiak called a strained right calf muscle.

Kubiak said the injury wasn't serious and that Foster is day-to-day. He left the field on a cart with a bag of ice on his right leg.

Foster had a league-leading 351 rushing attempts for 1,424 yards and 15 touchdowns in 2012, when he started all 16 regular-season games for the first time in his four pro seasons.

In three years as Houston's fulltime starter, Foster has averaged 318.7 carries for1,421 yards.
