England's Ashes blueprint has been put under scrutiny after an injury scare threatened to derail their plans, with Mark Wood's potentially significant hamstring issue casting doubt over his participation in the opening Test against Australia at Perth's Optus Stadium.
The team's strategy for the series had been revealed just days earlier, featuring five seam options including Ben Stokes and a no-rotation policy, but any carefully laid plans now appear to be hanging by a thread.
Stokes himself performed well, taking six wickets as England bowled out the Lions XI - which included several members of the Ashes squad - for 382 on the first day. However, there are concerns about Wood's fitness following his injury, and if he does not recover in time, it could be a major blow to England's plans.
Wood was one of three England bowlers who appeared fragile during the practice match, alongside Stokes and Jofra Archer, while Gus Atkinson impressed with his short-pitched bowling.
England's batting lineup looked solid however, although the Lions' top-scorer Ben McKinney had a decent outing before being dismissed by Josh Tongue.
Durham's McKinney scored 67, while Somerset's Thomas Rew added 55 to his total as he became Gus Atkinson's scalp. Another player, who could potentially replace Wood in the team, Jordan Cox took 53 runs off England bowlers.
However, if Mark Wood does not return to action on time, it is possible that the balance of England's strategy could be disrupted.
The batting lineup could also see a change with Jacob Bethell coming close to displacing Ollie Pope, who has struggled in his last few appearances for the team.
While Brook remains optimistic about England's chances, he admits that the side will face a tough test against Australia at Perth's Optus Stadium.
