EDEN PRAIRIE, Minn. — The Minnesota Vikings have signed quarterback Gus Frerotte — again.

Frerotte's contract was finalized today. The 14-year veteran served as Daunte Culpepper's backup for the 2003 and 2004 seasons, and now he's in line to do the same for incumbent Tarvaris Jackson.

The Vikings were looking for more polish at the position, and possibly someone to push Jackson for the job after Brooks Bollinger and Kelly Holcomb failed to produce when Jackson was struggling or injured.

Bollinger is still on the roster, but Holcomb was released.

Frerotte has 82 NFL starts. He last played for St. Louis, starting three games in 2007 and throwing his 100th career touchdown pass.
