Olly Stone has been sidelined for two weeks due to the reoccurrence of the stress fracture in his lower back that will force him to miss the second Ashes Test against Australia at Lord's.
Stone made his Test debut last month against Ireland where he took three wickets and impressed with his high bowling speeds.
"It's really disappointing for Olly that he's been ruled out of action for such an important two weeks of cricket because of a reoccurrence of his back injury," said Warwickshire sport director Paul Farbrace.
Stone has repeatedly found himself subject to injuries as his first Test appearance was delayed after suffering a back injury on tour with England to the West Indies earlier this year having initially been part of the squad.
Archer has made a strong case for earning a spot in the playing XI since he struck a century for Sussex's second XI on Tuesday along with a brilliant spell of 6-29.
Stone might not be fit in time to participate in the third Ashes game at Headingley scheduled to begin on August 22.
