Jacksonville, FL (SportsNetwork.com) - Jacksonville Jaguars wide receiver Stephen Burton will miss Sunday's contest against the Arizona Cardinals with a concussion.
Burton, who did not practice all week, has been limited to 76 yards on eight receptions in four games this season, returned to action last week after a five-game absence. He posted one catch for 11 yards in a 29-27 win at Tennessee.
In addition, wideout Stephen Williams (Achilles), who was limited on Wednesday and did not participate the last two days, will not play.
Offensive lineman Will Rackley (head) was limited the first two days and missed practice on Friday and is doubtful for the contest.
Linebacker Paul Posluszny has been deemed questionable due to a concussion suffered in last week's victory. The Penn State product did not see the practice field this week.
Running back Maurice Jones-Drew is probable with a knee injury. The eight-year pro improved every day this week, missing practice on Wednesday, taking limited reps on Thursday and participating fully on Friday.
