The Dolphins opened the regular season in the annual Thursday NFL Kickoff Game against the Pittsburgh Steelers on September 7.  Even though newly acquired QB Daunte Culpepper was doing a pretty good job on the pass and RB Ronnie Brown provided a touchdown, the Dolphins trailed 14-10 going into the second half, until Brown got another rushing touchdown.  Unfortunately, an 87-yard touchdown pass to Steeler tight end Heath Miller and a 42-yard interception return by ROLB Joey Porter sealed the Dolphins' fate. Head coach Nick Saban attempted to challenge Miller's touchdown reception on the grounds that he stepped out of bounds before reaching the goal line (which television replays proved was correct), however, officials failed to see Saban throw the red flag before the Steelers kicked the extra point, and the Dolphins were unable to challenge the call. Of more concern than simply the loss was the performance of the Dolphins' prized offseason acquisition. Daunte Culpepper threw two interceptions, and floated several passes that were almost intercepted. This performance has sparked debate as to whether he will be able to return to his 2004 form or if he will have a repeat of his terrible 2005 campaign. One positive from the game was slot WR Wes Welker. He had 67 yards receiving and set up the first TD for Miami.
