Clarke needs to shuffle his pack with Peter Odemwingie serving a three-match ban.
"Yeah, Romelu could come into the picture," Clarke told the Albion website.
"He's been in my thoughts since the minute he came into the club. I've said before that I've been delighted with Shane (Long). The decision to take him off at half-time at Fulham was tactical.
"We couldn't get enough support to him in the first half and then obviously when we went down to ten men we needed a different type of forward.
"I've got Marcus Rosenberg chomping at the bit so I've got plenty to chew over before the weekend."
