NEW YORK (Reuters) - Minnesota Vikings running back Adrian Peterson, who owns the National Football League's (NFL) single-game rushing record, has agreed to a long-term contract extension, the team said on Saturday.

The terms of the deal were not disclosed but reports said Peterson, who was in the final year of his contract, agreed to a seven-year extension.

"Adrian's performances on the field have given fans so much excitement since he first joined us as a rookie," Vikings owner Zygi Wilf said in a statement. "His talent and determination are remarkable and we are proud to have him be a part of the family for years to come.

Peterson was selected by the Vikings in the first round of the 2007 Draft, has been a Pro Bowl selection in each of his four seasons and set the single-game rushing record when he ran for 296 yards against the San Diego Chargers in 2007.

His signing came just over a week after Chris Johnson, who has more rushing yards than any other player in the NFL over the past three seasons, agreed to a six-year, $56 million extension with the Tennessee Titans.

The Vikings open their 2011 NFL season on Sunday against San Diego.
