MIAMI (CBSMiami) – Miami Dolphins running back has no problems running into 300 plus pound linemen, but he’s about to take on one of his biggest challenges at home.

Bush confirmed Tuesday that he and his girlfriend, Lilit Avagyan, are expecting a baby, Bush said on the Paul & Young Ron Show. The two have been dating for almost a year.

Bush knows exactly what he’s hoping for with the baby.

“I’m hoping for a boy because if it’s a girl, I’m going straight to the gun shop to buy some guns,” Bush told the radio hosts.

Bush is playing the best football of his career over the last two seasons. He was finally made a feature back last season and responded with more than 1,000 yards rushing. This season, he’s run for 417 yards in five games. He’s averaging just less than 5 yards per carry, and has three rushing touchdowns on the season.
