Some fantasy league football teams took a hit Sunday when Minnesota Vikings running back Adrian Peterson rolled his ankle during the first quarter against Oakland.
 
They may suffer even more after Vikings coach Leslie Frazier said Monday the star running back suffered a high ankle sprain and is wearing a boot this week, which makes his availability uncertain for Sunday’s game against Atlanta. Frazier labeled the injury as a Grade 1 sprain, according to the Associated Press.
 
Peterson’s 872 rushing yards rank sixth in the NFL, but his 11 rushing touchdowns is tops in the league.
 
"The good news is there's nothing more serious than that," Frazier said in the AP story "He'll recover from it. It's just the amount of time that he'll miss. We'll have a better indication toward the end of the week."
 
But all indications are the fifth-year running back will be held out at least a week to give the injury time to heal. It’s not like the Vikings are competing for a playoff spot at this point.
 
"We don't want to put him at risk. You know how valuable he is to our team and our franchise," Frazier said. "So we'll monitor where he is and try to make a good decision with what's best for him and what's best for our team as well."
