Zuerlein became of the NFL's most respected kickers during his stint with the Rams from 2012-19. In 2017, he was voted a first-team All-Pro and earned a Pro Bowl berth.
Following a 2018 campaign in which a groin injury sidelined him for five games, Zuerlein converted just 24 of 33 field-goal attempts last season (72.7%), his lowest percentage since 2015. He also hit all 42 extra-point tries.
Overall, the 32-year-old has converted 82% of field-goal attempts throughout his career.
The Cowboys endured kicking issues throughout 2019, as their 75% conversion rate was the seventh-worst mark in the NFL.
This offseason, Dallas also signed veteran kicker Kai Forbath to a one-year, $1.18-million deal with $137.500 guaranteed.
