WHILE Jarryd Hayne will have to learn the game from the bottom up, one Aussie who needs no introduction to the NFL is 23-year-old Jesse Williams.

Born on Thursday Island, Williams was raised in Brisbane before becoming the first indigenous Australian to be given a football scholarship to a US college with Arizona Western.

His defensive abilities saw him recruited by the highly-rated University of Alabama Crimson Tide in 2011, spending two seasons there before being chosen in round five of the 2013 NFL draft by the Seattle Seahawks.

Seattle, of course, went on to win the Super Bowl last season, but the 147kg defensive end was forced to sit out the entire campaign with a knee injury.

Rated a strong chance to make his debut this season, he is now back in Brisbane undergoing rehabilitation for another knee complaint.

Seahawks coach Pete Carroll said he was confident the player nicknamed "Tha Monstar" would earn a spot on the team once he regained full fitness.

"Jesse was good enough to join us ... it's just unfortunate that he's been banged up," Carroll told APN.

"He did really well when he was healthy and able.

"He'll miss the season, his second one in a row, which is tough for him.

"But he's a great kid and he works really hard."
