Crucial Carlton duo Sam Docherty and Blake Acres find themselves under injury clouds following Friday night's thrilling semi-final win over Melbourne, while a star defender is understood to have avoided a concussion.

The Blues, who triumphed over the Demons by two points at the MCG on Friday night, have progressed to a preliminary final berth against the Brisbane Lions at the Gabba next weekend.

However, Michael Voss may be without one or more of his stars after multiple incidents placed their playing statuses in question.

Docherty appeared to dislocate his shoulder during the second quarter on Friday, with broadcast footage displaying the ugly sight after a contest with Melbourne's Judd McVee didn't go to plan.

The Blues' medical staff assessed the veteran at half-time and he managed to valiantly play out the remainder of the match, which included a critical goal assist to Acres, who kicked the game-winner with a minute remaining in the game.

Voss addressed the injury issues facing his side, starting with Docherty's sore shoulder.

"Obviously Doc with a shoulder, we'll assess that, so he's the major one at this point in time, [we] always wait until Monday with that one [because we're] never too sure, so I'll say just Doc at the moment (in terms of injuries), but we'll wait til Monday," Voss said.

"It seemed like it (the shoulder) actually pulled up not too bad. I'm sure he'll get to work pretty hard on what that shoulder [issue] is and get himself right for next week."

As for key defender Jacob Weitering, the Carlton key defender received a suspected head knock in the final quarter, courtesy of Demon Joel Smith.

Seen to be left groggy from the collision, the key defender attempted to jog it off but was clearly affected by the incident.

According toย AFL.com.au,ย the Blues have since cleared Weitering of a concussion, with the incident involving Smith understood to have hit Weitering's neck.

Meanwhile, Acres' shoulder concern reared its head in the first quarter, with the issue clearly bothering him throughout the contest. However, it didn't stop him from kicking the goal that sealed Carlton's preliminary final fate.

Carlton will travel to Brisbane next week, looking to book a Grand Final ticket.
