Toronto Raptors guard Patrick McCaw is expected to miss several weeks of action due to an injury that requires surgery on his left knee, according to Shams Charania of The Athletic and Stadium.

McCaw has been dealing with the left knee ailment throughout the early stages of this season. He was held out of Saturday night's loss to the Milwaukee Bucks. The former UNLV standout had been ruled out indefinitely and was set to see a specialist to address the issue, according to Blake Murphy of The Athletic, and now he's going under the knife.

In his two appearances with the Raptors this season, McCaw posted averages of 4.0 points on 60.0 percent shooting from the field (33.3 percent from beyond the arc), 3.0 rebounds, 1.5 assists and 1.5 steals in 20.0 minutes per outing.

With McCaw sidelined, the Raptors will likely call on Terence Davis, Matt Thomas and Stanley Johnson a bit more. Toronto's depth behind a strong top half of the roster is a bit questionable.

The Raptors claimed their first NBA championship last season, defeating the Golden State Warriors in six games. Toronto (4-2) is playing well through the early stages of this campaign, despite the fact that Kawhi Leonard decided to join the LA Clippers over the summer.

Toronto will be back in action on Wednesday night, as they're scheduled to host the Sacramento Kings. Tip-off inside Scotiabank Arena is set for 7:30 p.m. ET.
