Tannehill missed the past five games due to a capsule (shoulder) injury. The 30-year-old quarterback ramped up throwing during the team's bye week and did extensive work during Tuesday's practice.
Gase looked "good" in practice and is confident about Tannehill's shoulder holding up.
"He's done a good job of rehabbing," the coach said. "... He's been waiting for this week to come for a while."
As of late last month, Tannehill was still feeling pain while throwing, but Gase said Tuesday the quarterback didn't complain of discomfort during the bye.
Tannehill's season opened as a mixed-bag, completing 65.9 percent of his passes for 972 yards with eight touchdowns and five interceptions in five games before suffering the injury. After guiding Miami to a 3-0 start, however, the QB succumbed to breakdowns on his offensive line and reverted to being a check-down quarterback. In his final two tilts, Tannehill completed just 31 of 55 passes for 285 total yards with three interceptions and one touchdown.
At 5-5, the Dolphins remain in the thick of the muddled AFC playoff race. Managing a banged-up receiver corps, Miami needs a boost from Tannehill's return to keep their playoff hopes alive.
