Felix Jones Injury: Updates on Eagles RB's Ribs

Philadelphia Eagles running back Felix Jones left Thursday evening's preseason game against the Carolina Panthers with an injury to his ribs.

The team's official Twitter page broke news of the development, which is the latest in a slew of medical trials and tribulations for Jones:

Before leaving the game at Lincoln Financial Field, Jones had carried the ball four times for 14 yards and caught one pass for three yards.

Considering that the Dallas Cowboys selected Jones in the first round of the 2008 NFL Draft, he's had a slightly disappointing career to date.

Jones has his work cut out for him to make an impact in the Eagles backfield, with Pro Bowler LeSean McCoy, talented youngster Bryce Brown and even 2012 undrafted free agent Chris Polk in front of him on the depth chart.

Since he wasn't able to establish himself as the starter with the team that drafted him, fleeing to Philadelphia as a free agent this offseason was Jones' best option—and on a mere one-year contract.

Knee and ankle problems have hampered Jones throughout his previous five years in the NFL.

In spite of that, the 26-year-old still has averaged 4.8 yards per carry overall. He is also a threat to catch the ball out of the backfield, having grabbed as many as 45 receptions in a single season with the Cowboys in 2010.

However, a former first-round pick should not be entering his sixth season without a 1,000-yard season, but that is the case with Jones. This latest setback hurts his chances significantly of making the final 53-man roster.
