Harris (toe) will be reevaluated in three weeks, Eddie Sefko of the Dallas Morning News reports.
The Mavericks clarified Wednesday that Harris is battling a sprained big toe on his right foot, and he'll remain in a walking boot for three weeks before being reevaluated. While the timetable is still rather fluid, the minimum three-week timetable means Harris would likely miss at least the first 10 games of the season. In the veteran's absence, expect J.J. Barea and Seth Curry to pick up extra minutes behind the starting backcourt of Deron Williams and Wes Matthews.
Kessel picked up a power-play assist in Tuesday's 3-2 win over Florida.
He's scored two goals and two assists in seven games and all four points have come courtesy of the power play. Coach Mike Sullivan continues to tinker with his even-strength lines. Kessel started on the "HBK" line Tuesday and then moved to Evgeni Malkin's line later in the contest.
Greiss gets the start against the Canadiens on Wednesday.
Greiss will make his first consecutive starts of the season as he appeared in Sunday's 6-3 winner over the Wild. Neither netminder has established himself as a true No. 1 for the Isles, so expect the 30-year-old to continue splitting time with Jaroslav Halak. Montreal currently lead the NHL in goals per game with 3.83 so owners may want to pursue other goaltending options Wednesday.
Williams (head/neck) will not practice Wednesday.
Williams had to go to the hospital Sunday after taking a cheap and unnecessary hit from Miami's Jarvis Landry. While Rex Ryan hasn't ruled Williams out yet for this week's game against the Patriots, you can bet the team will take extra caution with Williams given the sensitive nature of the injury and his scary past with head/neck issues.
