The flak jacket Ty Montgomery would have to wear if he's cleared to play Sunday at Minnesota is bulky and sits just below where the Green Bay Packers running back would need to tuck the ball when he runs.

But coach Mike McCarthy isn't concerned that it could present a ball-security problem for Montgomery, who hasn't shown a proclivity for fumbling since he became a full-time running back early last season.

Montgomery practiced this week with a large pad around his lower ribs that was fashioned by long-time team equipment manager Gordon 'Red' Batty and his staff.

"Red Batty and our equipment staff, I think they have about 130 years of NFL experience -- some crazy statistic like that," McCarthy said Friday. "Those guys are in good hands, no different than our medical staff. Whatever our players need to be comfortable and be protected or whatever their need is, it's always done with a level of expertise and experience that doesn't really put us in that type of situation."
