Montreal Canadiens defenseman Andrei Markov took part in practice with contact on Monday.
The practice of this kind is Markov's first since November. During that practice, the 33-year-old's surgically repaired right knee swelled significantly, causing him to be shut down.
Coach Randy Cunneyworth told TSN that Markov's involvement on Monday was "business as usual."
Markov has been sidelined since suffering an ACL and MCL tear against the Carolina Hurricanes on Nov. 13, 2010.
He appeared ready to return to the lineup earlier this season but needed to undergo another surgical procedure in December.
The Canadiens signed Markov to a three-year, $17.25 million contract in June.
In 623 career games, Markov has collected 81 goals and 285 assists.
