THE WESTERN Bulldogs are breathing a sigh of relief after scans revealed exciting playmaker Jason Johannisen hasn't ripped his hamstring muscle off the bone.

The 23-year-old was expected to miss up to four months, but appears set to be back sooner with Saturday night's injury classified as a high-grade hamstring.

Western Bulldogs football boss Graham Lowe said the club would seek further medical opinion on how best to move forward. 

"He does have a high-grade hamstring injury, but he doesn't have separation of the hamstring from the bone," Lowe told the club's website.

"We're considering our options, seeking further specialist advice, and we'll know in the next 24 hours exactly how we plan to move forward."

Key forward Tom Boyd will also seek further opinion on a shoulder knock he received against the Blues and hasn't been ruled out of this Saturday night's clash with the Brisbane Lions.

Matt Suckling's ankle has pulled up well from the weekend and he is unlikely to spend time on the sidelines.

The club expects All Australian defender Easton Wood and goalsneak Tory Dickson to be available for selection to face the Lions.

Wood has missed the past two weeks with a hamstring injury while Dickson got through a game in the VFL at the weekend after quad and adductor injuries had seen him sidelined since week one of the NAB Challenge.

The club also confirmed on Monday that skipper Robert Murphy and defender Josh Prudden would have traditional knee reconstructions.

The duo joins Clay Smith, Roarke Smith and Tom Liberatore as Bulldogs to succumb to a dreaded ACL tear in the past 18 months.
