Minnesota Vikings running back Adrian Peterson was absent from his side's practice this afternoon due to personal reasons.

Peterson was recently rocked by the news that his two-year-old son had died on Friday, although he did play in Sunday's 35-10 defeat to the Carolina Panthers.

Vikings coach Leslie Frazier refused to confirm whether the reigning NFL MVP's absence was linked to his son's tragic death, but did reveal that Peterson was expected to return tomorrow.

"He and I will talk later today, but I expect him to be back tomorrow, ready to go. This is a very difficult situation, without question. And it has many challenges, many challenges," Frazier told reporters.

The Vikings currently sit bottom of the NFC North with a 1-4 record and will face the 0-6 New York Giants in their next match.
