Hawthorn will be without forward Chad Wingard for its Round 2 clash against Sydney after he suffered a minor calf injury in Sunday's loss to Essendon. 

The Hawks had just the one injury concern from the club's season opener, with the 29-year-old coming off during the third quarter. 

Hawthorn's High Performance Manager Peter Burge said Wingard is expected to be back fully training next week and be available for selection ahead of Round 3 against North Melbourne. 

"Chad reported a cramping sensation when he was taking a kick, it was with his calf and the signs were quite minimal," Burge said. 

"But given Chad's history medically, it was decided to just take the conservative option and rule him out of the rest of the game.

"He has since had scans and it's a very, very low-grade calf strain. He won't play this week, but I'll expect he'll be running by the end of this week, be back fully training next week and available for Round 3."

Meanwhile, Harry Morrison will be available to play this week after facing some back soreness. 

"Harry's hamstring injury is fine, but then during last week he developed some back soreness," Burge said. 

"He wasn't able to complete full training on Thursday... it had settled by the weekend, but he hadn't completed main training so we decided to delay his return by a week."

Burge also provided an update on key forward Mitch Lewis who has faced a slight setback.

Lewis' rehab with his ACL has been going strongly, however, during his re-loading phase he has faced a slight issue with his other knee. 

"A little bit of fluid (in the other knee) has developed, it's from a previous historical issue in the past," Burge said. 

"It's certainly not bad or anything like that, it's just put us in a bit of a holding pattern for the last week, so we've delayed his return timeframe by a week to allow us a little bit more time to make sure we get a good result."
