Week 4 of the NFL season is here and there's no better place to get your lineup ready than by watching Fantasy Football Live. Starting Thursday at 7 p.m. ET, Yahoo Fantasy analysts Andy Behrens and Matt Harmon will join host Jason Fitz to preview the week ahead and help with your sit-start decisions. They will also hit on some of the biggest questions we need answered.

• What should we expect from the Lions and Packers in their TNF matchup?

• Can Trevor Lawrence and the Jaguars get on track as they head to London?

• Is top pickup De’Von Achane a must-start against the Bills?

• What fantasy grades do members of the rookie class deserve?

NBC Sports fantasy analyst Lawrence Jackson Jr. will stop by for a conversation about optimal FLEX plays for the week.

You can watch FFL on YahooSports.com, the Yahoo Sports App, the Yahoo Fantasy app, YouTube, Twitter and Facebook.
