The club is delighted to announce the signing of left-back Anthony Callaghan from Washington.
The 22-year-old, formerly of Darlington and Sunderland, is available to make his debut for the Mariners at Dunston UTS on Tuesday.
Callaghan has expressed his excitement after joining the Mariners, who he faced as a Washington player last month.
He said: “I’m over the moon to join and I can’t wait to get started.
“I played against Shields earlier this season and I could see that they were a great side, so I’m looking forward to being part of it.
“There’s a lot of competition for places so I’m prepared to get my head down and work hard to get into the side and keep my place.
“The team is doing great, so hopefully I can help them continue that.
“I can’t wait to put the strip on and get involved, get mucked in and get to know everybody.”
Welcome to the club, Anthony!
