The phones of multiple D.C. United players went missing from the team's dressing room during last week's match at Mexican side Queretaro.
The players discovered the thefts after losing 2-0 to Queretaro in the first leg of their CONCACAF Champions League quarterfinal.
"Unfortunately, a handful of phones were stolen from the locker room during our match against Queretaro," United spokeswoman Lindsay Simpson told the Washington Post, adding that a small amount of cash was also taken.
"CONCACAF was made aware of the situation. The club has been very apologetic and has willingly offered to replace all of the stolen property."
D.C. United coach Ben Olsen said he was satisfied with Queretaro's response, though he wasn't surprised by the incident.
"It's upsetting that stuff like that still goes down in CONCACAF," Olsen told the Post. "I've been going down to Central America for almost two decades, and stuff happens. It's part of CONCACAF. It goes into the lore of this great CONCACAF exploration."
United hosts Queretaro at RFK Stadium in the second leg of their quarterfinal on Tuesday.
