Broncos' Peyton Manning ties Brett Favre's all-time passing TD record

With his second touchdown pass of Sunday night's game against the San Francisco 49ers, Denver Broncos quarterback Peyton Manning has inched closer to sole possession of one of the NFL's most prestigious records.

The 39-yard connection with Wes Welker marks the 508th passing touchdown of Manning's career, tying former Packers quarterback Brett Favre for first on the NFL's all-time list.
