Miami Dolphins coach Adam Gase says Ryan Tannehill might return this week against the Detroit Lions, but there's uncertainty about the severity of the quarterback's injury to his throwing shoulder.

Gase described Tannehill's status as day to day and said he didn't know whether there was a chance the injury could be a long-term issue. Gase said he's confident Tannehill will play again this season.

The situation is unusual because Gase said Tannehill's shoulder got worse as last week progressed. Tannehill was ruled out of Sunday's game against Chicago hours before kickoff, and replacement Brock Osweiler led the Dolphins to a 31-28 overtime victory.

Gase quashed any potential quarterback controversy by saying Tannehill will return to the lineup when he's healthy.
