DAVIE http://www.tampabaybuccaneersteamonl...edwards-jersey , Fla. (AP) — Miami Dolphins quarterback Ryan Tannehill has been ruled out of Sunday’s game against the New York Jets, meaning Brock Osweiler will start for the fourth game in a row.Tannehill, recovering from an injury in Week 5 to his throwing shoulder, was limited in practice Wednesday. He has begun throwing, but improvement in his shoulder has been unpredictable http://www.tampabaybuccaneersteamonl...att-gay-jersey , coach Adam Gase said.“Some days it feels a lot better,” Gase said. “Some days it doesn’t feel as good when he’s throwing.”The Dolphins are 4-4, and 1-2 with Osweiler starting. His passer rating of 93.8 is slightly higher than Tannehill’s 92.9.“This sport is so special, and you never know when you’re going to get another opportunity,” Osweiler said. “So when you do get the opportunity to play http://www.tennesseetitansteamonline....-brown-jersey , shoot, man, I play every single play like it’s my last. I’m playing as hard as I possibly can, so hopefully I never have to go back to the bench.” Raiders running back Isaiah Crowell tore his Achilles earlier this week and the team formally ended his season on Friday by placing him on injured reserve.In between those two developments, the Raiders re-signed veteran running back Doug Martin to join first-round pick Josh Jacobs http://www.tennesseetitansteamonline...-hooker-jersey , Jalen Richard, DeAndre Washington and Chris Warren as options in the backfield. Gruden talked up all of the backs, including the role Martin can play as Jacobs learns the ropes as a professional.“Doug will be able to come in here and be a great mentor to Jacobs,” Gruden said, via NBCSportsBayArea.com. “He knows the system. He has produced in the system. Doug has had some real highs and some real lows in this league. He’ll be a great resource to our young back Taylor Rapp Jersey , and he can still play. We’re happy to have Doug back and disappointed for Isaiah.”Gruden also referred to Martin as a three-down back, which, as Josh Dubow of the points out, is a bit curious given the fact that he only played 21 snaps on third down last season. Richard had 155 snaps in that role and the presence of all the backs in Oakland means there’s going to be some experimenting to do before making any calls about who is doing what in September.
