The tight end hinted Saturday he might not attend the team's mandatory minicamp, which begins Wednesday.
"Who knows? I might go to see my mother in Texas. I have no idea," Shockey said.
Shockey, in New York for a promotional event, shared his gripes with reporters.
"Unlike the Giants, I'm going to be quiet," he said. "They've released multiple things about myself and if you look back into the media, there's always a source. Well, I'd like to know who this source is and we'll go over here and we'll deal with it ourselves, because I haven't said one negative thing toward the Giants in the newspapers."
Shockey was making his first public comments since breaking his leg in December. The Giants went on to beat the Patriots to win the Super Bowl. Afterward, Shockey was a no-show for the team's victory parade in New York, its visit to the White House and its championship ring ceremony.
In the weeks leading up to the draft, the New Orleans Saints and several other teams approached the Giants about a trade for the oft-injured Pro Bowler. The Giants listened, but that was it.
If he does attend the minicamp, Shockey said he'll be limited.
"Obviously. I'm not 100 percent and if I do show to minicamp, it's going to be, I wouldn't imagine me doing much, just getting treatment on my leg," Shockey told reporters.
