St George Illawarra coach Paul McGregor has named a 22-man squad for the Dragons' Round 13 clash against the Wests Tigers at ANZ Stadium, Olympic Park on Saturday, June 3.

Four players – Josh Dugan, Tyson Frizell, Jai Field and Blake Lawrie – will potentially back up from their respective State of Origin fixtures on Wednesday night, which has allowed McGregor to name 22 players rather than the usual 21.

Tariq Sims has been named in the back row, with Jacob Host listed in the 17, for Frizell who sits in the reserves.

Skipper Gareth Widdop and Dugan may also make their long-awaited NRL returns from knee and cheekbone injuries respectively after also being named in the reserves.
