Englewood, CO (SportsNetwork. Mattia Perin Jersey .com) - Denver Broncos running back Montee Ball practiced in a helmet and pads for the first time since suffering a groin injury last month and said he expects a battle to get his starting job back from Ronnie Hillman. Ball was officially limited in practice on Wednesday, according to the Broncos. He was hurt during a game against Arizona on Oct. 5 and has been sidelined the past four weeks while Hillman has seen the bulk of the carries for the AFC West leaders. Its been tough because you always want to contribute as much as possible and this is the longest Ive ever been out in my entire life, Ball said. (Its) my longest and most serious injury ever but I have to battle through it. Ball averaged just 3.1 yards per carry over Denvers first four games, rushing for 172 yards and one touchdown. Hillman has averaged 4.3 yards per carry in six games and has rushed for at least 100 yards twice since Ball has been out, scoring three touchdowns. The running game has been a lot better since hes been in there, so Im not going to sit here and lie to myself, said Ball. So when I get back Im going to contribute as much as possible and try to get that spot back. Ball said he will tell the Broncos when hes ready to play again. Im going to listen to my body, he said. Whenever you guys see me out there Ill be a hundred percent.
