New Brisbane recruit Marcus Adams won't feature at the beginning of the season following recent knee surgery, as reported by the Herald Sun. 

There is no return date for the defender, who struggled with injuries during his time at Western Bulldogs, but proved he can be a reliable player in any back six.

It is likely Adams will return through the NEAFL for the Lions' reserves side, but it may not happen until April.

The league saw Adams burst onto the scene during the Bulldog's famous 2016 season, where he managed to play the opening seven matches of the season.

Adams had many breakout games in season 2016, including a 23 disposal, 15 mark performance against the Hawks. However, foot and shoulder troubles held the defender to just 11 games in his debut season, missing out on the 2016 premiership.

Brisbane traded for the West Australian during the off-season, offering up pick 32 to get deal over the line.

Although he's yet to play a match for the Lions, the absence of Adams spells trouble for coach Chris Fagan, who is still yet to lock-in the players in his side's spine for the upcoming season.

Along with former Docker Lachie Neale, Adams will likely shape as one of Brisbane's most important players as they look to  challenge for their first finals campaign since 2009.
