The Miami Dolphins have made a minor transaction in preparation for Sunday's game against the Buffalo Bills, waiving cornerback Evan Oglesby and promoting defensive end Ryan Baker from the practice squad.

An undrafted rookie out of Purdue, Baker signed with the Dolphins following the 2009 NFL Draft. He failed to make the active roster following the preseason and has been on the team's practice squad since the beginning of the regular season.

Oglesby's release comes just four days after he was signed by the Dolphins as a free agent.

A four-year veteran with the Bills, Cowboys and Ravens, Oglesby remained unsigned after being waived by Baltimore during final cuts on Sept. 6.

Analysis

This transaction was made purely for this weekend's game and could very well be reversed early next week.

Reserve defensive end Lionel Dotson is likely out against Buffalo (he's officially listed as doubtful with an ankle injury) and the team obviously felt Baker's experience in the system since April was more valuable tomorrow than new arrival Ikaika Alama-Francis could be.

Baker will likely serve as the No. 4 defensive end behind starters Kendall Langford and Randy Starks and top backups Phillip Merling and Tony McDaniel, who is now also serving as the top backup to nose tackle Paul Soliai.

Meanwhile, Oglesby was the logical choice to make room for Baker. He is not in demand and should clear waivers easily. He was also signed just this week and wasn't going to play or contribute against the Bills anyway.

In all likelihood, Baker will be waived when Dotson is healthy and then re-signed to the practice squad, at which point I expect Oglesby to be re-signed.
