Kahlil Lewis left it all on the field in his XFL debut –- literally.

The Houston Roughnecks receiver was spotted projectile vomiting during the Fox broadcast, as he was lined up for a first-quarter play in the team’s opener Saturday against the LA Wildcats at TDECU Stadium.

Lewis, 22, appeared to puke twice before the snap.

The former Cincinnati star had two first-quarter catches for 18 yards. The Houston-LA game was the second of opening day for Vince McMahon’s revamped football league, which began a week after the Super Bowl.

The DC Defenders defeated the Seattle Dragons in the first game, during which Seattle center Dillon Day dropped an F-bomb during an in-game sideline interview.
