History
In 1982, with 58 seconds left in the NFC title game, Joe Montana found Dwight Clark for the winning score against Dallas. “The Catch” sent the 49ers to their first Super Bowl and helped launch a run of four titles in the 1980s. — (voice only)
Keep in mind
The need for a backup is real. Purdy hurt a toe, came back, hurt it again and, in Shanahan's words, "he's been out for the last month."
