Edmonton Oilers forward Taylor Hall is expected to miss four weeks after injuring his left knee in a game on Saturday.
General manager Craig MacTavish confirmed the injury timeline Tuesday morning through a post on the team's Twitter feed.
Hall, the first overall pick in the 2010 draft, has three goals and five assists in nine games this season. He was hurt on an innocent-looking play in Edmonton's 3-1 win at Ottawa.
MacTavish also said that forward Ryan Smyth is expected to be out for a week with a groin injury. The Oilers have recalled forwards Ben Eager and Tyler Pitlick from the minors.
