Quarterback Colin Kaepernick is a free agent after opting out of his San Francisco 49ers contract Friday.

Kaepernick made a meteoric rise with the 49ers under coach Jim Harbaugh, leading them to the 2012 NFC title and a close loss to Baltimore in the Super Bowl. But his career spiraled in recent seasons, and he was benched for journeyman Blaine Gabbert.

His decision leaves the team with no quarterbacks on the roster. Gabbert and Christian Ponder also are free agents.

Kaepernick, 29, has indicated he plans to stand for the anthem next season.

Colin Kaepernick has officially opted out of his contract.
