And two days after the island nation was devastated by an earthquake, donations to help relief efforts were flowing from around the sports world.
Garcon said Thursday he received calls earlier in the day from relatives, who let him know they had survived the earthquake that devastated Haiti two days earlier.
Garcon said his mother received a call from a relative Wednesday night.
"I heard from some family, got some good information," he said. "We're still looking for the rest of them."
Garcon attended high school in Florida, but his parents emigrated to the U.S. from Haiti, and most of his relatives still live there. Garcon, visibly drained after Thursday's practice, said he's thankful for the concern that people have shown for Haiti.
"It's nice to get support from a lot of people," he said. "I really appreciate it. We need a lot more."
Garcon is expected to play in Saturday's AFC divisional playoff game against the Baltimore Ravens, but he's struggling to focus.
"You've got to deal with it," Garcon said. "It's kind of tough, but there's not much you can do about it."
Garcon has used Twitter to get people to help the country, and he's giving autographed items to fans who donate money to the relief effort.
"Eventually, I'll go down there," he said. "My mom's going down there soon. I have other family members going down there, and people from church are going down there."
The NFL is partnering with the Red Cross, CBS and FOX to air public-service announcements during the divisional playoff games this weekend to promote the Red Cross' text-to-give line. Also, all four home teams (Colts, San Diego Chargers, Minnesota Vikings and New Orleans Saints) will promote the same text-to-give message via video board and public-address announcements.
Both the Colts and Chargers have said they will be hold collection drives at their games to support Haitian relief efforts. Colts ownership has kicked off their drive with a $10,000 contribution to the American Red Cross.
