St George Illawarra coach Paul McGregor has named his mandatory 21-man squad for the Dragons' Round 3 clash against the Cronulla Sharks at Southern Cross Group Stadium this Sunday, March 19.

The Dragons are unchanged following their disappointing 34-16 loss to the Parramatta Eels last weekend in Wollongong.

Utility Jai Field (ribs) has been named in the squad as a reserve after he was ruled out late from last weekend's game, as has back-rower Tyson Frizell (concussion) who failed to finish last week's game.

Skipper Gareth Widdop was hopeful of the Dragons bouncing back against their local rivals this weekend.

"We were certainly inconsistent. Right from kick-off, we made it hard for ourselves," Widdop said.

"For us this weekend it's about focusing on what we have to do. It's going to be a tough match so we'll have to go there with a good attitude.

"The boys are really excited for it."
