Sheffield Eagles have signed hooker Keal Carlile, who was released by Hull KR earlier this week.
The former Bradford and Huddersfield player, who lost his place at the Robins to new arrival Shaun Lunt, has signed a contract with the Kingstone Press Championship club until the end of 2016.
Sheffield Eagles have signed former Huddersfield Giants forward Tony Tonks.
The 29-year-old front rower has made 141 Championship appearances for Halifax and his previous club Featherstone Rovers, scoring 19 tries.
He is the Eagles' seventh signing of the close season, joining Blake South, John Davies, Steve Thorpe, Jamie Langley, Ben Musolino and former Halifax team-mate Rob Worrincy.
"Games against Sheffield have always been tough battles," said Tonks.
"You can see there is a real togetherness and a real strong culture at the club, and I want to be a part of that.
“Having spoken to Mark Aston you can see he is building something here. He has made some really good signings, and the players that are already here are class acts as well.
"He is taking steps to improve the club and the squad so I’m looking forward to being involved.
“I think top four is definitely achievable. When you look at the sides that will be competing at the top end of the table, I don’t think Sheffield are far away from them at all.
"As long as all the new lads fit in well, which I’m sure we will, I think we will be right up there."
Plans for a new £50 million community sports park in Sheffield were unveiled today.
It will be known as the Olympic Legacy Park, and will be built on the site of the old Don Valley Stadium. It is hoped it will be fully operational in early 2016. ITV Calendar reporter Chris Dawkes reports:
Sheffield Eagles have announced they will be returning to the site of the old Don Valley Stadium when they move into a new community stadium in the Olympic Legacy Park.
The Eagles have secured a £6m investment to fund the building of stadium, which will feature a high quality synthetic pitch, an impressive main stand, a 50-bed hotel, catering and hospitality areas, and facilities developed in partnership with Sheffield’s second University Technical College.
Plans for the new Legacy Park are well advanced and the first phase of the re-development is already underway with the building of a new through school catering for children from 2 to 16 years. The school will open its Primary phase in September 2015, with the second phase opening a year later.
At the same time, Sheffield’s second University Technical College (UTC) will open on the same site, specialising in human sciences and digital technologies.
Hooker Gareth Owen has become the third Salford player to join Championship Grand Final winners Sheffield Eagles on a season-long loan.
The 21-year-old, who has made 36 Super League appearances but is now the Red Devils' third-choice hooker, follows team-mates Will Hope and Jon Ford to Owlerton for 2014.
"I'm excited to be joining the Eagles," said Owen, who is set to make his debut against Swinton on Sunday. "They had a great season last year, winning the Championship for a second successive year and I hope I can help them defend the trophy again in 2014."
Defending champions Sheffield Eagles will be without Scotland second-rower Alex Szostak for the 2014 Championship season after he opted to concentrate on his day job as a genetic technologist at a children's hospital.
Szostak, 27, who will use the break to develop business interests in Lancashire and progress his career within the NHS, has made 148 appearances for the Eagles since joining them in 2008 and played in all three of their Championship Grand Finals.
He was in the Scotland team that reached the quarter-finals of the 2013 World Cup.
"I have had a fantastic time over the last five years playing for Sheffield Eagles and Scotland and I've decided the time is now right to take a break from rugby league and focus on other commitments," said Szostak, who will consider returning for the 2015 season.
"Winning back-to-back championship with the Eagles and representing Scotland against New Zealand in the quarter-finals of the World Cup was a great way to end 2013 and finish on a incredible high."
With the re-structuring of the top two divisions it is a big year for our clubs in the Championship - rugby league's second tier.
Although promotion to the Super League won't come into effect until next year, each and every club will be doing their best to ensure they aren't one of the 5 clubs relegated to the third tier.
The Sheffield Eagles are back to back champions, and head coach Mark Aston says the pressure will be on this season:
Salford Red Devils duo Jon Ford and Will Hope have joined Championship club Sheffield Eagles on season-long loan deals.
Ford, 21, a centre or winger, and second-row forward Hope, who turned 21 yesterday, have both been included in Brian Noble's Super League squad for 2014 but are well down the pecking order at Salford.
Former Great Britain centre Keith Senior is to return to Sheffield Eagles as part of the Championship's club back-room staff.
Senior, 37, who was a member of the Eagles side that beat Wigan in the 1998 Challenge Cup final at Wembley, will become one of two assistants to head coach Mark Aston, while maintaining his day-to-day role at the Leeds Rugby Foundation.
Senior, who played with Aston at Sheffield from 1995-99, hung up his boots in 2011 after becoming the first player to reach 500 appearances in Super League.
