Samuel Callaghan Brenner (born April 27, 1990 in Oceanside, California) is an American football center who is currently a free agent. He was originally signed by the Miami Dolphins as an undrafted free agent in 2013. Brenner played college football at Utah.
Brenner played high school football at Oceanside High School in California, where he was a two-time all-league selection and a second-team all-state selection as a senior in 2007. He was twice named his team's Most Valuable Offensive Lineman and played in the California All-Star Game following his senior season. He was named a scholar leader athlete by the Walter J Zable/ San Diego chapter of the National Football and College Hall of Fame. Additionally, he was a finalist in the county wide Silver Pigskin, the first offensive lineman ever so honored by the voting coaches and sports reporters. Brenner's team won the 2007 California Division II State Bowl.
Although Brenner signed with the University of Utah in 2008, he did not enroll until January 2009. As a true freshman, Brenner played primarily on special teams in all 13 games and added 53 snaps on offense. As a sophomore in 2010, Brenner served as the team's top backup offensive lineman and started at left tackle in the team's Las Vegas Bowl loss to Boise State.
Brenner started 12 games at right guard and one at tackle as a junior in 2011, grading out as the team's best offensive lineman in five games and ranking second on the team in total snaps despite exiting the season finale with a neck injury. As a senior in 2012, he started the first two games at right guard followed by 10 at left tackle, allowing just one sack on his way to second-team All-Pac-12 honors.
2013 NFL Draft
At Utah's Pro Day prior to the 2013 NFL Draft, Brenner ran a 5.03 40-yard dash and did 29 bench reps of 225 pounds. He was regarded as a late-round or undrafted prospect, drawing style comparisons to Zane Beadles and T. J. Lang.  After going undrafted in the 2013 NFL Draft, Brenner signed with the Miami Dolphins as an undrafted free agent.
Brenner entered his first pro training camp as the lone backup at center behind Mike Pouncey, facing competition from second-year guard Josh Samuda. He was released by the team during final cuts before the regular season and was re-signed to the practice squad on September 2. After 10 weeks on the practice squad, Brenner was promoted to the active roster, replacing offensive tackle Will Yeatman (placed on injured reserve with a torn ACL) and providing depth at center with starter Mike Pouncey listed as questionable for the team's Week 11 contest with an illness.
