PHILADELPHIA Michael Vick has required four medical tests and completed four passes in the first two preseason games.

That’s an ominous sign for the Philadelphia Eagles.

The three-time Pro Bowl quarterback left Monday night’s win at New England after injuring his ribs on his sixth play. He lasted just six plays against Pittsburgh before leaving with an injured left thumb.

X-rays on Vick’s ribs at the stadium were negative, and an MRI and CT scan on Tuesday revealed he has no broken bones or fractured cartilage. Vick has a contusion of his ribs and of the soft tissue surrounding it. He also needed X-rays on his thumb when he got hurt in the first game. They also were negative.

Vick missed three games because of rib injuries in each of the past two seasons.

Vick has led the offense to just one first down in 12 plays so far.

Around the league

Denver: Free agent safety Jim Leonhard practiced Tuesday for the first time since undergoing a right knee operation in December.

Leonhard is a seven-year veteran who spent the past three seasons as a fan favorite with the New York Jets following stints in Buffalo and Baltimore.

Indianapolis: Andrew Luck is likely to see his most extensive playing time of the preseason at Washington.

Colts coach Chuck Pagano says he plans to play most of his starters, including Luck, into the second half Saturday afternoon.

Pagano’s plan is to use his starters until halftime, make adjustments and send the Colts’ starters back out to see how they adjust.

Jacksonville: The Jaguars are going to be England's team. The NFL and the Jags announced Tuesday the team will play one home game in London for four years in a row.

The small-market franchise will play four games at Wembley Stadium, one every season beginning in 2013.

New York Giants: Despite developing a blood clot in his left leg a little more than a week ago, there is a chance New York Giants defensive tackle Shaun Rogers might play this season.

Giants coach Tom Coughlin said Tuesday that the 12-year-veteran got a second opinion about his injury, and the team has “a ray of hope” that Rogers will be able to get back on the field.

New York Jets: Nose tackle Kenrick Ellis will not be suspended by the NFL after the league completed its review of his legal situation following his guilty plea to misdemeanor assault and battery.

Ellis was sentenced to 45 days in a Virginia prison in May after a fight while in college at Hampton University in 2010.

Oakland: After missing all offseason workouts while recovering from shoulder surgery, center Stefen Wisniewski has now been sidelined more than a week with an injured calf sustained in the exhibition opener.

Pittsburgh: The Steelers and a related charitable foundation have dropped a trademark lawsuit after a man stopped selling “Terrible Towel” knock-offs in different languages.

Nick Rossi said last week he began making the towels to raise money for Italian earthquake victims a few years ago before expanding production to other languages including Spanish and Hebrew.

Washington: Clinton Portis is announcing his retirement, nearly two years after he played his last NFL game.

The Redskins said Tuesday that Portis and owner Dan Snyder will hold a retirement news conference Thursday.

Portis played two seasons with the Broncos and then seven with the Redskins. His 1,516 yards rushing in 2005 set a franchise record.

The Redskins cut Portis after a torn groin muscle ruined his 2010 season.

He was unable to find another team and ends his career 77 yards shy of 10,000, No. 27 on the NFL’s all-time list.
