Jason Roy passed a concussion test but will be assessed again on Thursday ahead of the start of the third Ashes match.
The England opener was struck on the side of the neck while batting in the nets at Headingley on Tuesday.
He came through his concussion examination on Wednesday but England will wait until the day of the start of the Test before making a decision on his participation.
Australia star Steve Smith, the leading run scorer in the series, has been ruled out of the meeting with a concussion suffered when he was struck by a Jofra Archer bouncer in the drawn second Test at Lord's.
Roy played an instrumental role in England's triumphant Cricket World Cup campaign but has struggled on his first foray into red-ball cricket.
He scored 72 in the second innings in England's win over Ireland in July, but Roy has just 40 runs to his name in the Ashes and contributed only two at Lord's.
