The Minnesota Vikings and second-round running back Toby Gerhart have agreed to terms on a four-year contract, Judd Zulgad of the Star Tribune reports.

Financial terms were not disclosed.

In just 38 games, and 26 starts, Gerhart ran for 3,522 yards, ranking second on Stanford’s all-time list. Gerhart’s 44 touchdowns are the most in school history, and his 1,871 yards on the ground in 2009 set the school’s single-season record.

Gerhart was a second-team All-Pac-10 in 2008, and earned first-team all-conference, as well as All-American honors after a 2009 season where the 6-0, 231-pounder was the Pac-10 Offensive Player of the Year, the Doak Walker Award (nation’s top RB), and placed second in balloting for the Heisman Trophy.

Gerhart joins a backfield that is headed up by Adrian Peterson, a three-time Pro Bowler and two-time All-Pro who led the NFL in rushing in 2008 and in rushing touchdowns last season. Gerhart is expected to back-up Peterson up, taking some of the short-yardage and goal-line pressure off Peterson.

With Gerhart signed, the Vikings' entire 2010 draft class before training camp officially begins.
