Injured Warwickshire all-rounder Keith Barker will miss this week's County Championship game against Somerset at Taunton.
After missing the first three games of the new season for the county champions with a hamstring problem, Barker made 45 and took four wickets on his return in last week's win over Durham.
But a side strain picked up on the last day limited his second-innings bowling.
The Bears are also without Ian Westwood (damaged ankle ligaments).
After injuring himself in training, the former skipper has been replaced by young all-rounder Ateeq Javid, who took four wickets for the Second XI against Scotland on Wednesday.
Skipper Jim Troughton is fit after treatment on a shoulder injury.
Warwickshire's form so far
- 24-27 March v MCC (Abu Dhabi). Won by an innings & 29 runs
- 2-7 April v Oxford MCCU (The Parks). Won by 21 runs

The Bears captain had to leave the field on the first day after landing on it awkwardly while attempting to take a catch.
Winter signing Oliver Hannon-Dalby returns after being left out for the Durham game.
Hannon-Dalby took five wickets on his Warwickshire debut against the MCC in Abu Dhabi, before claiming six more against the Oxford students in The Parks.
He then took his first Championship wicket for the Bears in the rain-affected, season-opening draw against Derbyshire.
Fellow Bears paceman Chris Wright, the Bears' six-wicket second-innings hero against Durham on Saturday morning, says that it is the wicket-taking potential throughout the whole Warwickshire attack that is their strength.
"First innings against Durham it was Keith Barker and Chris Woakes who got the wickets. In the second innings, it was me. That's how we work," he told BBC WM.
"We were a little bit aggrieved to have lost that time against Derbyshire, arguably a side who we thought we could beat, whereas a draw against Durham would not have been the worst result.
"We thought that maybe we did not get enough and that we'd then let them get too many in reply, but we put that right, and it turned out to be a very good win."
