Willis wound up being signed to the practice squad, where he replaced fellow wideout P.K. Sam.
Finally, the team signed linebacker Robert McCune off the Washington Redskins practice squad and waived veteran Keith Newman.
The big move, though, was putting Culpepper on IR.
"Even though Daunte was making good progress in his rehabilitation, we both felt, along with our medical staff, that it would be very difficult for him to be ready to play in the next three weeks," Coach Nick Saban said in a statement. "Because it's important to have depth at the quarterback position the rest of the season, we all felt the best decision for the team was to place him on IR."
Culpepper wound up playing four games in his first season with Miami, completing 81 of 134 passes for 929 yards with two touchdowns and three interceptions. Ironically, his passer rating of 77.0 remains better than that of Joey Harrington, who's at 72.9.
But Culpepper was sacked 21 times in the four games he played, and his lack of mobility was the reason Saban decided to replace him following the Oct. 1 game at Houston.
The bad part about Culpepper now being done is that we'll have to wait until next year to really find out whether Culpepper can regain his full mobility in real-live action.
