INDIANAPOLIS The more productive half of the New England Patriots' two-headed tight end monster remains questionable for the Super Bowl.

Rob Gronkowski, who injured his left ankle in the AFC championship game against Baltimore, sat out the Patriots' 2 1/2-hour practice Wednesday at the Colts' facility.

"He's getting better, but we'll just take it day-to-day," Patriots coach Bill Belichick said.

Earlier Wednesday, Gronkowski said he had "not really" been able to do any running since getting injured, and expressed concern over his conditioning level.

"That's what I'm wondering, too," Gronkowski said. "But the training staff has us doing things to keep it up - eating healthy every single day, making sure you are not eating trash, just staying at your weight and doing what you possibly can do, so you can stay in shape."

Gronkowski teamed with Aaron Hernandez for 169 catches, the most by a tight end tandem in NFL history. Gronkowski finished the regular season with 1,327 receiving yards and a league-leading 17 touchdown catches, both records for a tight end.

New York coach Tom Coughlin said the Giants have prepared for different personnel sets, but expect to see Gronkowski on the field.

"Not to belittle the question, I really do think he'll play," Coughlin said.

BRING THE NOISE: Belichick had loud music blaring inside the Colts' practice facility, which the Patriots are using, to prepare for his team's first dome game this season. The musical selections included songs from Jon Bon Jovi - a friend of Belichick's who attended the Patriots' playoff win over Denver - and Madonna, who will perform at halftime Sunday.

"We can make it loud enough so that (the players) can't hear," Belichick told a pool reporter. "As long as they can't hear, you have to do silent communications whether it's on defense with hand signals or offense with tapping the center" for the snap.

DANCING WITH THE STAR: Giants receiver Victor Cruz has one of the game's best touchdown celebrations - a salsa dance that has become popular among New York's large Latin population, according to Cruz.

Cruz, who is of Puerto Rican descent, said an assistant coach encouraged him to do something in honor of Latin Heritage Month, which runs from Sept. 15 to Oct. 15.
