Rochdale have made three new signings ahead of the 2020 League 1 season.
Hooker Sean Penkywicz, 37, joins the Hornets having made more than 350 career appearances for Halifax, Huddersfield, Leigh, Toronto and Workington. He has earned four caps for Wales.
Brothers Lewis and Declan Sheridan arrive at the Crown Oil Arena from amateur side Rochdale Mayfield.
Hornets coach Matt Calland said: “Sean is a class player with a wealth of experience having played over 350 professional games.
“I am really looking forward to working with him again. He is a real character and a match winner.
“Declan has achieved so much in the amateur game. It is now the right time for him to challenge himself at a higher level.
“Lewis was at St Helens as a kid on their scholarship and was captain of Mayfield last season. He is a very versatile player who knows where the try-line is.”
