Port Adelaide have locked up the services of speedy winger Danyle Pearce for three years, while also securing assistant coach Jason Cripps for a further two.

The Power have battled a tide of negative news this week surrounding Shaun Burgoyne's decision to quit the club, but have managed to shore up their playing and coaching rosters elsewhere.

Pearce is important as one player capable of carrying on from where Burgoyne left off, though his ability to handle taggers will be severely tested again.

Other players to announce contract extensions on Friday were veteran forward Warren Tredrea, defender Michael Pettigrew, tagger Tom Logan and budding ruckman Matthew Lobbe.

Another assistant, Matthew Primus, declared he would be staying on at the Power earlier this week.

Pearce acknowledged the "re-building" Power were now striving simply to get back into finals contention after two years out of the top eight, and also said he now intended to be a one-club player.

"We're in a rebuilding phase at the moment and I'm excited to be apart of that as this new group strives to get the club back to playing consistent finals football," Pearce said in a statement.

Power football operations manager Peter Rohde was happy to have secured a number of key performers.

"Danyle is a very damaging player who is well respected by every other team, given that he is heavily tagged every week," he said.

"Michael Pettigrew is able to play back or forward, and has shown in the past he can be a good player in big games. We look forward to him taking the next step in his development.

"Tommy Logan is a hard-nut and has played some important roles for us this year while Matt Lobbe's improvement since transferring to West Adelaide in the SANFL mid-way through the 2009 season has been very impressive."
