An MRI turned up negative after practice, but Tannehill did suffer an ACL & MCL injuries last season on the same knee.
Salguero reports this "decision was made Friday evening made Friday evening when coach Adam Gase and Tannehill spoke about the options open to them". Tannehill will be placed on injured reserve, the person said.
That's quite an "if" though, as Cutler struggled through his five games last season, managing five interceptions and just four touchdowns. "It's more and more real".
Tannehill chose to avoid surgery after last season's injury. Miami moved quickly to address its quarterback situation, handing Cutler, 34, a one-year, $10 million contract.
Tannehill does have his flaws-including throwing at least 12 interceptions in each of his first five National Football League seasons-but he's had more positives than negatives throughout his career to this point. He worked so hard to be available for us and those guys did a lot of work during the offseason to get to this point.
"He's handling it good". He's trying to do everything he can to help Jay (Cutler) out and Matt (Moore) has done a great job. Matt has got more reps than he had past year at this point in training camp.
