"I'm improving every day," Gronkowski said. "The only reason it's getting so blown up is because it's the Super Bowl. It's just like any other injury during any other week."
Gronkowski, who suffered a high left ankle sprain in the AFC title game Jan. 22, said he could be anywhere from in perfect health to "2 percent" for the game, adding that it's still six days away.
The outgoing Gronkowski smiled frequently from the podium during his hour-long appearance that opened with a question, of course, about how he was feeling.
"Good. How are you feeling?" he replied.
At one point, Gronkowski even put on a red tri-cornered hat, reminiscent of those worn by the original patriots during the era of the American Revolution.
"He's obviously making progress," quarterback Tom Brady said of his key pass-catcher. "He's out of his boot today, which makes me feel a lot better. I told him he should write like `Mom I love you' on his sock or something because I'm sure there'll be a lot of pictures of his sock.
"If anybody wants to be out there, it's him. No one's as tough as him."
Gronkowski was careful not to convey an overly optimistic attitude about his chances of playing, repeatedly saying he was working with the Patriots training staff and approaching the situation on a day-to-day basis.
He also was non-committal when asked if he could play if he had the injury during the regular season.
"I couldn't answer that," he said. "It's not a regular-season game. It's the Super Bowl this week and (we're) just preparing like it's a big game and it's the biggest game. It ain't no regular-season game. So you've got to treat it a lot differently."
Gronkowski set an NFL record for his position this season with 17 touchdown catches and had 90 receptions overall for 1,327 yards. He's made a team-high 15 catches for a 15.5-yard average and three touchdowns in the postseason. He also developed into a powerful blocker.
He missed the Patriots last three practices on Thursday, Friday and Monday. They didn't practice on Tuesday.
But many of his teammates are confident that he'll be ready to play.
"Rob's a big boy. He's tough and everything else, so I'm not too worried about him," wide receiver Wes Welker said. "I know he's going to give his best out there and do whatever he can do to help us win the game."
"We're trying to get everybody to play," linebacker Tracy White said. "We're not too worried about Gronkowski. He'll be out there."
Gronkowski has started every game this season and was healthy for nearly every practice before the ankle injury.
