Miami Dolphins coach Adam Gase said Monday that quarterback Ryan Tannehill does not have a torn ACL but has an ACL/MCL sprain in his left knee and will not need surgery.
"Better than we thought yesterday," Gase said.
The coach said he did not know how long Tannehill will be out.
The Dolphins were bracing for the worst when Tannehill injured his left knee in Sunday's 26-23 victory over the Arizona Cardinals.
Tannehill was hit low late in the third quarter by Cardinals defensive tackle Calais Campbell and was knocked out of the game.
