The Daily Mail says Bowyer wants to sign Wilbraham on loan even though the 6ft3ins marksman's last league goal came for Norwich against Fulham in March 2012 - 30 games ago.
Despite his lack of goals, Wilbraham's hold-up play is regarded highly by team-mates and the 33-year-old featured in Palace's Championship play-off win against Watford at Wembley and two of their opening three games in the Premier League this season.
The Rovers manager said: "Fingers crossed but we're hopeful of getting in one in before Saturday. There are a number of names on my list and hopefully we can get an answer off a few people."
