Nat Fyfe is expected to spend some time on the sidelines after sustaining a hamstring injury against Richmond at Marvel Stadium on Friday night.

The Fremantle skipper was subbed off in the third term of the clash, replaced by medical substitute Travis Colyer on the ground.

A ‘disappointed’ Fyfe was just six games into his return after missing the first half of the season with a back injury, playing his first game of 2022 in round 13 against Hawthorn.

Longmuir said it appeared to be a regulation hamstring injury and is hopeful that the dual Brownlow medallist will return within the next few weeks.

“I think it will be a standard hammy, that was the call from the doctors after the game,” Longmuir told SEN’s Crunch Time.

“You never really know with these things, so we’ll get him back and get it scanned and let everyone know.

“He's come back from hammy’s before, and we hope he only misses the two or three weeks, can get a game in before the bye and starts getting his mojo back again.

“He was disappointed after the game, but he was around his teammates and supporting them well.”

The ‘untimely’ injury comes as Longmuir felt Fyfe was starting to embed his role since his return to the line-up.

“It’s not ideal clearly, he’s missed so much footy, and we feel like we were just starting to get on top of his form and his role,” Longmuir said.

“Even last night it was untimely because we started getting field position in that second half and…having someone who can take a contested mark like him would have been handy to have.

“It’s going to make things a little bit trickier towards the end of the year, but he’s a pro and he’s going to rehab it really well and his fitness won’t be an issue.”

While having to split the two premiership points with the Tigers, Longmuir said he was left impressed by the energy brought throughout the final quarter by his young group.

He also highlighted the pivotal Michael Frederick smother that prevented Richmond’s Noah Balta from converting a score that would’ve seen the opposition take the lead with only minutes remaining on the clock.

“I thought we saw some signs of our energy lifting last night, Richmond got on top through the middle period…but I thought our energy to hang in there was really strong,” Longmuir said.

“Sometimes with a young group when the pressure comes on you can go a little bit insular and that affects your risk-taking and decision-making, so we just wanted to make sure we kept on spreading the ground.

“We talk about being on task and in the moment all the time and that (the Frederick smother) was a great example of it.

“Frederick and Schultz were ready to go and as soon as the umpire raised his arms off, they went, and it was clearly game saving for us.

“The energy is something we need to build on because it’s only going to get tougher and the games are only going to get bigger, so we need to make sure that we lean in on each other.”
