An eight-year veteran, Rosenthal played for the Minnesota Vikings the past four seasons, but he was released March 1. He figures to compete for the starting right tackle spot, assuming the team follows through on its plan to switch Vernon Carey to left tackle as it reshapes its offensive line under first-year head coach Cam Cameron.
Rosenthal, 29, participated Friday in the team's initial minicamp session under Cameron.
The former Notre Dame standout has appeared in 89 games and started in 58 of them. He logged 15 starts for the Vikings over the past two years. Rosenthal has played left guard and right tackle during his career and started 12 or more games in three seasons. He started 16 games each in 2002, with the New York Giants, and in 2003 with Minnesota.
Known mostly as a power blocker, Rosenthal, a fifth-round choice of the Giants in the 1999 draft, was also sought by the Tampa Bay Bucs after Minnesota released him. His contract for 2007 includes a $40,000 signing bonus.
Miami also re-signed unrestricted free agent safety Travares Tillman, who appeared in 30 games for the Dolphins over the last two seasons, on Friday. A seven-year veteran, Tillman signed a one-year contract that includes a base salary of $720,000.
Tillman, 29, previously played for Buffalo (2000-02) and Carolina (2003-04). He has 17 starts in his two seasons in Miami but lost the No. 1 job at strong safety to Yeremiah Bell halfway through the 2006 campaign. His stint with the Dolphins includes 96 tackles, three interceptions and three passes defensed.
The former Georgia Tech safety has 175 career tackles, four interceptions and 10 passes defensed for his career. He is expected to serve as a backup and on special teams in 2006.
