The Jacksonville Jaguars have revealed that Maurice Jones-Drew's status for this Sunday's game against the Seattle Seahawks is uncertain.

The running back, who was diagnosed with a strained ankle tendon following last week's 19-9 loss to the Oakland Raiders, missed a second day of practice yesterday.

The 28-year-old is still suffering from swelling in his ankle, which will have to go down if he is to feature for the AFC South side this weekend.

Jones-Drew missed the majority of the 2012 season with a Lisfranc injury.
