Jets playing musical right tackles during Breno Giacomini's absence

FLORHAM PARK, N.J. -- Sunday's wake-up call, Day 4 of New York Jets training camp:

What's happening: The Jets will be in pads for the second straight day, but there's a good chance they will wind up indoors again, as the weather forecast is ominous. They will be on the field at 1:50; practice is open to the public with a valid ticket.

What's hot: The offense will look to rebound after a shaky day, especially in the red zone. Quarterback Geno Smith struggled, throwing two interceptions in one seven-on-seven period. He threw another on the final play of practice, from inside the 10-yard line with only a few seconds left in the "game." It was Smith's first bad practice. The Jets had one of the league's most efficient red zone offenses last season, so there's no reason to panic. ... The Jets have been rotating three different players at right tackle during Breno Giacomini's absence -- Brent Qvale, Ben Ijalana, and rookie Brandon Shell, who also is getting a look at left tackle. None of them have legitimate NFL experience, so the team would be in a bind if Giacomini's back injury becomes long-term. He's expected to miss at least a week, but that appears to be a conservative timetable. Asked if he's concerned about Giacomini's availability for the season opener, coach Todd Bowles said, "Not at this point. ... As it goes forward, we'll see how it progresses. There may be worry or concern, but it gives us a chance to look at other guys." Giacomini hasn't been spotted on the sideline during practice, usually an indication that an injury is serious. ... With Matt Forte (hamstring) and Khiry Robinson (leg) on the sideline, recently-signed veteran Bernard Pierce is getting a lot of work. He's a Temple product, which doesn't hurt his chances. Bowles is a Temple alum.
