Head coach Kyle Shanahan revealed on Wednesday that Coyle also has a broken bone in his back — T4 compression fracture.
"Six weeks until he can have contact again," Shanahan said. "He will recover sometime this year but it's going to be at least six weeks before he can have a chance to play football."
Coyle signed a three-year extension with the 49ers on March 14 after initially joining the team on a one-year deal on March 10, 2017. He, along with safety Marcell Harris (hamstring) and linebacker Dekoda Watson (hamstring), is eligible to return to the active roster after spending eight weeks on injured reserve.
The 49ers also announced several other roster moves on Wednesday, including the signing of linebacker Terence Garvin to a one-year deal. His signing was first reported earlier during the day by Ian Rapoport of NFL Network.
In addition to the Garvin signing, the 49ers promoted offensive lineman Najee Toran from the practice squad to the active roster. The team signed wide receiver Frank Stephens to replace Toran on the practice squad.
The 49ers initially signed Toran as an undrafted free agent on May 1. He was released as part of the 53-man roster cut-down on September 1 and then signed to the practice squad the following day.
Garvin will wear number 57.
Toran will wear number 66.
