Friday was the last day for a settlement to be worked out, otherwise Gadsden would have spent the entire season on injured reserve or had to waived off injured reserve. In either case, he would have been ineligible to play for the Dolphins this season.
Now, Gadsden can re-sign with the team after 10 weeks and that's certainly a possibility depending on injuries and/or the performance of young wide receivers J.R. Tolver and Sam Simmons.
The Dolphins also reached an injury settlement on Friday with linebacker Byron "Bam" Hardmon, but that one wasn't nearly as significant as the situation with Gadsden.
This has been, of course, one ridiculously frustrating year for Gadsden, who didn't get the extension he wanted last fall, didn't get the free agent offer he wanted this offseason, and finally had to settle for the Dolphins' relatively low-end contract proposal in June.
Finally, there was the ankle injury he sustained early in camp which has kept him sidelined.
There's no exact word yet as to when Gadsden will be ready to play football again, but it looks like at least another few weeks. It's not terribly likely another team will sign him before he's eligible to rejoin the Dolphins, but injuries around the league obviously could change that.
