Peterson has pledged $1 million to the Oklahoma athletics department, his launching pad for a stellar NFL career.
The university announced the donation Thursday. It will go toward construction of a new student housing facility and establish a football scholarship endowment in Peterson's name. The university says this is the largest gift to the athletics department from a former football player.

The Minnesota Vikings have signed Bowman to a one-year contract.
Bowman led the Bears with six interceptions and 10 passes defensed in 2009. But he lost his starting job in 2010 and never regained it in the past two seasons. In Minnesota, he'll be relied upon to add depth to a Vikings secondary that struggled last season. The 27-year-old likely will also be used on special teams.

The Minnesota Vikings have re-signed Henderson to a one-year deal.
Henderson was one of the Vikings' most consistent players on defense last season. He was fourth on the team with 91 tackles and also had eight tackles for loss in his first season as a full-time starter.

Henderson is returning to the Minnesota Vikings.
The 25-year-old linebacker has agreed to terms on a one-year deal to stay with the team that signed him as a rookie free agent in 2008. His agent group tweeted the agreement on Friday. Henderson played very well last season in his first chance as a regular starter, emerging as one of the team's most versatile defenders. Playing alongside his brother E.J., he had 91 tackles and two forced fumbles in 15 games.
