Jacksonville Jaguars running back Maurice Jones-Drew has a hamstring injury and underwent a magnetic resonance imaging exam today.

Jones-Drew's injury isn't believed to be serious and he said he expects to play against the Buffalo Bills next week.

Jones-Drew rushed for a season-high 103 yards against the Houston Texans, his first 100-yard game since the third week of last season. He's rushed for 719 yards this season.

"The guy tried to take my legs out and I just tried to jump-cut underneath him," Jones-Drew said. "Then when I tried to explode out, it just grabbed a little bit. I'll be fine."
