Jacksonville Jaguars guard Will Rackley will miss three to four weeks with a high ankle sprain, the team said at its Wednesday practice. Rackley went down in practice on Tuesday and was later seen on the field with crutches. The injuries up front are a concern to head coach Mike Mularkey.

Mularkey says it's a concern that O line has so many guys dinged up. Rackley will be out 3-4 weeks with right ankle. OUCH!

In the meantime, Jason Spitz will work in Rackley's spot with the starters. A third-round pick in 2011, Rackley beat out Spitz for a starting job last season, and went on to make 14 starts as a rookie.
