Former Oregon State quarterback

will sign a two-year deal with the Miami Dolphins today, according to a source close to the situation.

Moore, who spent the previous three seasons with the Carolina Panthers, arrives in Miami today to sign a contract worth $5 million with incentives that could push it as high as $7.5 million.

The incentives are mostly playing-time based, which means Moore would have to unseat incumbent starter

, who threw for 3,301 yards and 15 scores while leading the Dolphins to a 7-9 record.

about acquiring quarterback

. The addition of Moore probably ends those talks. Had Miami landed Orton, a source said Moore would have been in play with the Broncos, as well as San Diego.

Moore, who entered the league in 2007 with Dallas as an undrafted rookie free agent, last year signed a one-year deal with the Panthers worth $3 million deal as a restricted free agent. Moore beat out rookie

but struggled, completing 55.2 percent of his passes for 857 yards and five touchdowns with 10 interceptions over six games for an offense riddled with injuries.

Clausen eventually replaced Moore but didn’t perform any better and the Panthers finished 2-14. In April Carolina selected Auburn quarterback Cam Newton with the No. 1 overall pick making Moore expendable.

Miami would like to see Moore duplicate his performance at the end of the 2009 season when he led the team to victories in four of its final five games and finished the season with a 98.5 passer rating. Moore threw for 1,053 yards and eight touchdowns with two interceptions.
