Crawley have signed former Albion midfielder Gary Dicker until the end of the season.
He was on a short-term deal with Rochdale, which was due to expire next month.
The move means a swift return to Sussex for the Irishman, who was with the Seagulls for four years.
Reds boss John Gregory said: “He is a great addition to our squad. He is a ball-playing midfielder with a great work ethic. We’re delighted to have him.”
