Jones and Hester participated fully in practice Friday after being limited the last two days with ankle injuries.
Shembo has a sore knee and Ishmael a sore ankle. Ishmael has stepped in for William Moore, who's out the next eight weeks with a shoulder injury.
Jones, a 2012 Pro Bowl selection who missed most of last year with a broken right foot, leads the NFL with 11 catches of 20 or more yards.
Hester, the league's career leader in touchdown returns with 20, is the No. 3 receiver with Harry Douglas ruled out.
