The Brisbane Lions have locked in three key players, with Harris Andrews, Ben Keays and Sam Skinner signing contract extensions.

Andrews, who was already contracted until the end of 2018, has put pen to paper and will remain at the Lions until at least 2021.

Keays and Skinner have both recommitted until the end of 2019.

Selected at Pick No.61 in the 2014 National Draft, Andrews has played 47 games since his debut against Richmond at the Gabba in Round 3, 2015.

The defender, a graduate of the Hyundai Help for Kids Lions Academy, was voted as a member of the Club’s Leadership Group this season for the first time.

Brisbane Lions General Manager of Football David Noble said he was excited to see Andrews continue to develop as one of the Club’s key defenders.

“It was important for us to secure Harris’ services,” said Noble.

“As a Queenslander he is a great reflection of our commitment to drafting and retaining local talent.

“Harris will continue to grow as a leader of this Club and is a big part of our future.”

The Lions again showed their commitment to nurturing local talent when they selected Ben Keays at Pick No. 24 in the 2015 National Draft.

Keays entered the Lions Academy as a 14-year-old, graduating from the Academy the same year as Eric Hipwood, who signed a contract extension with the Lions in 2016.

Keays has played 23 games since his debut in Round 6, 2016 against the Sydney Swans at the Gabba.

“Ben has already shown us some glimpses of his ability and we look forward to him playing many senior games for us,” said Noble.

A promising defender, Skinner has recommitted to the Club despite a year still to run on his contract.

Skinner has successfully got through his past two NEAFL matches on the way back from a second knee reconstruction.

He was due to debut in July last year before he tore his ACL at training. The 19-year-old spent the early part of his time at the Lions in rehab from an ACL injury sustained playing for Vic Country in 2015.

Skinner was selected at pick No.47 in the 2015 National Draft and came to the Club halfway through his rehabilitation.

Brisbane Lions List Manager Dom Ambrogio said it was Skinner's professionalism and commitment in the face of some difficult times that was most impressive.

"We’ve been really impressed with Sam," said Ambrogio.

“Despite the setbacks he has shown outstanding professionalism, character and commitment.

"Sam is competitive and aggressive, he will shore up our key defensive stocks for the longer term.

"We can't wait to see what he can do."
