CONROE, Texas (AP) —Vikings running back Adrian Peterson has avoided jail time with a plea agreement reached with prosecutors to resolve his child abuse case. Peterson was indicted in September on a felony charge of injury to a child for using a wooden switch to discipline his 4-year-old son earlier this year. The All-Pro running back says he never intended to harm his son and was disciplining him in the same way he had been as a child growing up in East Texas.

The boy suffered cuts, marks and bruising to his thighs, back and on one of his testicles, according to court records.

Peterson has been on paid leave. League spokesman Brian McCarthy says Peterson's situation, including court records, will be reviewed before a decision is made on his status.

Polamalu injured the knee in the second quarter of Sunday's 43-23 victory over Baltimore. The 33-year-old walked off the field and returned briefly before heading to the locker room. Polamalu, who has 51 tackles this season, will be replaced by Will Allen on Sunday.
