The Cowboys are adding a kicker in the aftermath of Brett Maher's meltdown in the Wild Card round. Dallas has signed veteran Tristan Vizcaino to the practice squad. Maher is the first kicker to miss four extra points in any NFL game since 1932. Despite his struggles in the Cowboys' 31-14 win over the Buccaneers on Monday night, the team has said that they are sticking with the 33-year-old this week. Vizcaino has converted 11-of-12 field goals and 15-of-20 extra points in 10 career games for four different franchises.
