Daunte Culpepper announced the end of his short-lived retirement on Thursday via e-mail.
In a report on NFL.com, the nine-year veteran wrote, "Now that there are some real opportunities that match my desire to play, I will choose the one that is the best fit for both the team and me so that I can continue my NFL career."
Culpepper was contacted earlier in the week by the Kansas City Chiefs, who were forced to sign Quinn Gray on Wednesday after quarterbacks Brodie Croyle and Damon Huard suffered season-ending injuries on Sunday against the Titans.
The 31-year-old Culpepper played in seven games last season -- six starts -- for the Oakland Raiders, completing 108-of-186 passes for 1,331 yards with five touchdowns and five interceptions. He was placed on injured reserve with the club with a strained quadriceps, clearing the way for No. 1 overall draft pick JaMarcus Russell to play.
The Raiders did not re-sign Culpepper, who played last season on a one-year contract, and the former Minnesota Viking and Miami Dolphin did not catch on with another team and decided to retire in September.
Culpepper's rise as an elite quarterback came to a halt after he tore three ligaments in his right knee in 2005. After a career year in 2004 -- completing 69.2 percent of his passes for 4,717 yards with 39 touchdowns and 11 interceptions -- Culpepper's 2005 season was disappointing even before he hurt his knee, as he had thrown 12 interceptions to only six touchdowns in seven games.
He demanded a trade in the offseason, and the Vikings dealt him to the Miami Dolphins, where his struggles continued. Culpepper lasted only four games with the Dolphins in 2006 before he was benched and eventually placed on injured reserve. The Raiders signed him prior to the 2007 season.
Culpepper is the all-time Vikings leader in completion percentage -- connecting on 64.4 percent of his passes -- and also rushed for a franchise record 2,476 career yards by a quarterback. For his career, he threw for 22,422 yards and a 63.8 completion percentage, with 142 touchdowns and 94 interceptions.
