[UPDATED with official announcement]

For 10 years, Tally Hall has made a living stopping shots. Now, he’s going to stop bad guys.

The longtime MLS goalkeeper, who joined D.C. United this spring but did not make any appearances, announced his retirement Friday. He did not go into detail about his future plans, but multiple sources said he plans to pursue a career in law enforcement.

With starter Bill Hamid and backup Andrew Dykstra recovered from long-term injuries, United signed Hall, 31, on April 1 to provide a veteran presence behind second-year pro Travis Worra. Worra performed well enough to keep the starting job until Hamid returned in late May from a knee ailment.

“Tally has been a tremendous presence in the locker room this year,” Dave Kasper, United’s general manager and VP of soccer operations, said. “His leadership, especially with the younger goalkeepers, has been immensely valuable and we wish him all the best in his future endeavors.”

The Seattle native starred at San Diego State and played two seasons for Danish club Esbjerg before signing with the Houston Dynamo in 2009. From 2011 to 2014, he was Houston’s first-choice keeper, made two MLS all-star teams, started in two MLS Cup finals, and earned U.S. national team call-ups.

An ACL injury prematurely ended his 2014 campaign in late August. Two months later, the Dynamo traded him to Orlando City, which was building the roster for its 2015 expansion season. He debuted in May and ended up making 23 starts before tearing meniscus in the same knee late in the season. Orlando did not exercise his contract option.

In eight MLS seasons, he started 153 regular season matches and recorded 40 shutouts. Hall also made 15 postseason starts, with five clean sheets.

In Houston, he had strong ties to military causes, most notably Banded Brigade Outdoors, a nonprofit outfit that organizes outdoor activities, such as hunting, fishing and target shooting, for active and retired servicemen and their families. Hall’s brother was in the Air Force and Alaskan air guard, and both his grandfathers served in the military.

Hall was due to earn $153,750 in overall compensation this year, according to the MLS Players’ Union.
