WEST Coast forward Jamie Cripps missed the Eagles' flight to Brisbane on Friday afternoon after being stung by a stingray on Friday morning.

Cripps spent all day at West Coast headquarters getting his foot treated by club medical staff after he was injured during a recover session at the beach. He was forced to miss the earlier flight but did board a later flight.

He will be assessed further when he arrives in Brisbane but is expected to take his place in the line-up to face the Brisbane Lions at the Gabba on Sunday.

It was a big day for Cripps after the Eagles confirmed that the speedy small forward had signed a three-year contract extension.

Cripps had been due to come out of contract at the end of this season but is now tied to the Eagles to the end of 2018.

"It's great to get the deal done," Cripps told the Eagles' website on Friday.

"I'm really looking forward to being a part of this group as we build towards something special. 

"We have an exciting young list and are single-minded about where we want to go. I think we're the fourth or fifth youngest squad in the AFL and it's great to be part of it." 

The West Australian, who turned 23 on Thursday, joined West Coast in the 2012 trade period after playing 16 games in two seasons with St Kilda. 

The versatile half-forward enjoyed a career-best year last season, finishing 10th in the Eagles' best and fairest after playing 19 games and kicking 27 goals.

Cripps has not missed a game this season and opened the year with a personal best five goals against the Western Bulldogs in round one before booting another two against Carlton the following week. 

The former East Fremantle player has played 37 games for the Eagles and 53 overall. 

He was pick No.24 in the 2010 national draft after representing Western Australia in that year's NAB AFL Under-18 Championships.

The Eagles traded pick No.40 to St Kilda for Cripps, which the Saints used to select Brodie Murdoch in the 2012 draft.
