Fremantle trio Matt Taberner, Cam McCarthy and Brennan Cox, all first choice tall forwards from 2018, face a battle for one remaining tall forward berth this year after coach Ross Lyon revealed his plans for three tall forwards.

Speaking to the AFL website Lyon named the trio and Jesse Hogan and Rory Lobb as contenders for spots. But with Hogan and Lobb priority signings - Hogan as the primary tall forward and Lobb as the likely forward/ruckman, the pressure will be on McCarthy, Cox and Taberner to nab the other spot.

“We’ve just got to make sure we’re not too tall,” Lyon said.

“Assuming they’re all available, we’re definitely going to try and work with the three talls in.”

“They’re all a little bit different... but there’s pressure on for spots.”

“But the critical (thing) is going to be make sure we’ve got ground level support, otherwise the ball will be just swept away. That’s just as important for us.”

The Dockers already appear to be moving to address their ground level forward pressure with accountable midfielder Bailey Banfield spending in attack in training drills.

Taberner, 25, kicked 10 goals from nine games last year, McCarthy kicked 19 from 17 games. Cox, still just 20, kicked 18 goals form 16 games but could also be used in defence.

Meanwhile Lyon said the serious hamstring tendon injury to Connor Blakely was “significant” because it compounded injury concerns to Stephen Hill who is expected to miss the first two games as he gets over quadriceps surgery.

Lyon said the pair were the most obvious replacements for the departed dual Doig Medallist Lachie Neale.

“We think (David) Mundy will spend more time midfield, so if we can start with a starting line-up of (Nathan) Fyfe, Mundy, (Andrew) Brayshaw, (Reece) Conca and Adam Cerra running through, we think we’re pretty healthy through there,” Lyon said.

Meanwhile the Dockers have announced the re-signings of Taylin Duman and Stefan Giro until the end of the 2021 season.

Both played 10 games with Duman, 20, impressive in a number of matches as a defender.

“It was really good to finish off the year against Collingwood strongly and, hopefully, I can use that momentum and use that belief that I’ve gained to fight for a round one spot this year,” Duman said.

“I’m really excited to extend with Freo. The mood at the club is really strong at the moment.”

Giro, 19, has emerged as the best runner at the club and was mentioned by Lyon as a player adding depth midfield.

“I’m looking forward to competing for a spot in the team. I can’t wait to get the JLT series underway and see how I go from there,” he said.
