Houston Texans running back Arian Foster sent out a tweet that he is OK a day after leaving Sunday's game against the Minnesota Vikings with an irregular heartbeat. Foster carried the ball 10 times for 15 yards and made two receptions for 14 yards before exiting in the third quarter after experiencing an irregular heartbeat. Houston lost 23-6. "I appreciate all the concern and support," Foster wrote. "I am doing well. Saw a cardiologist today and everything is back to normal." Foster experienced the problem before during practice, but called Sunday's incident a "minor situation." Foster has run for 1,328 yards with 14 touchdowns this year. The AFC South champs finish the regular season against the Indianapolis Colts this Sunday.
