Hall sustained the injury during Saturday's game against the Ottawa Senators. Ottawa defenseman Eric Gryba is being credited with inflicting the injury, as he connected on a hit at the midway mark of the second period. Hall remained in the game for a period of time before being slashed by Kyle Turris, albeit on his right leg.
The Canadian Press reported that Hall left the arena on Saturday with a brace on his knee. The Oilers announced that Hall had returned to Edmonton to undergo an MRI on Sunday, which produced the projection provided on Tuesday. This marks the third substantial injury to the team's top group of forwards, as Sam Gagner is still out with a broken jaw and Ryan Nugent-Hopkins missed the start of the season because of shoulder surgery.
Hall has recorded eight points (three goals, five assists) over the span of nine games this season.
