2015 season Showers was signed as an
undrafted free agent by the
Dallas Cowboys after the
2015 NFL draft on May 9. Although he passed for 125 yards, one touchdown and one interception in preseason, he made the coaches take notice with his
special teams play and versatility on the scout team. On September 5, he was waived and signed to the
practice squad two days later. On December 25, he was promoted to the active roster along with
defensive tackle Casey Walker, after the Cowboys placed
tight end Gavin Escobar and
quarterback Tony Romo on the
injured reserve list. He was declared inactive in the last 2 games.
2016 season In 2016, he moved up on the depth chart when backup quarterback
Kellen Moore broke his right tibia during the first week of training camp and the Cowboys couldn't reach an agreement with the
Cleveland Browns to trade for backup
Josh McCown. After Moore's injury, he competed with rookie quarterback
Dak Prescott for the backup job behind starter Romo. Several reports from August, indicated that Showers outperformed Prescott, showing greater accuracy and a quicker release in training camp. However, the Cowboys coaching staff made the decision to start Prescott in the team's preseason opener at the
Los Angeles Rams. Working with the Cowboys' first-team offense, Prescott completed 10 of 12 passes for 139 yards and two touchdowns in one half of action. In that game Showers had a notable 45-yard pass to
Vince Mayle, while escaping a certain sack, although Dallas would lose the game 28–24. After Romo suffered a
vertebral compression fracture during the first quarter of the Cowboys' Week 3 preseason game against the
Seattle Seahawks, in light of Romo's projected 8- to 10-week recovery time, Prescott was named the starter for the beginning of the
2016 season. For the backup quarterback position, the Cowboys wanted to pair Prescott with a veteran, so they released Showers on September 4 to make room for
Mark Sanchez, signing him to the practice squad the next day. On October 7, it was reported that Showers would be switching positions from
quarterback to
strong safety, in order to give him a better chance to make the team.
2017 season On January 16,
2017, he signed a reserve/future contract with the Cowboys. On September 2, 2017, Showers was waived by the Cowboys and was signed to the practice squad the next day. He was released on September 12, 2017, but was re-signed a week later.
2018 season On January 1,
2018, he signed a reserve/future contract with the Cowboys. He suffered a torn left ACL in the second preseason game against the
Cincinnati Bengals and was placed on the
injured reserve list on August 20.
2019 season On February 4,
2019, he was activated from the injured reserve. He was waived/injured with a hamstring injury during final roster cuts on August 31, 2019, and reverted to the team's injured reserve list the next day. He was waived from injured reserve with an injury settlement on September 9. ==References==
